Повний текст джерелаWe develop a homotopy theoretical version of classical Morita theory using the notion of a strong monad. It was Anders Kock who proved that a monad T in a monoidal category Σ is strong if and only if T is enriched in Σ. We prove that this correspondence between strength and enrichment follows from a 2-isomorphism of 2-catgories. Under certain conditions on T, we prove that the category of T-algebras is Quillen equivalent to the category of modules over the endomorphism monoid of the T-algebra T (I) freely generated by the unit I of Σ. In the special case where Σ is the category of Γ-spaces equipped with Bousfield-Friedlander’s stable model structure and T is the strong monad associated to a well-pointed Γ-theory, we recover a theorem of Stefan Schwede, as an instance of a general homotopical Morita theorem

Повний текст джерелаIn the thesis we generalize to a topos-theoretic setting two classical equivalences arising in the field of MV-algebras: Mundici's equivalence between the category of MV-algebras and the that of lattice-ordered abelian groups (1-groups, for short) with strong unit and Di Nola-Lettieri's equivalence between the category of perfect MV-algebras and that of 1-groups. These generalizations yield respectively a Morita-equivalence between the theory MV of MV-algebras and the theory Lu of 1-groups with strong unit and one between the theory P of perfect MV-algebras and the theory L of 1-groups. These Morita-equivalences allow us to apply the `bridge technique' whence to transfer properties and results from one theory to the other, obtaining new insights on the theories which are not visible by using classical techniques. Among these results, we mention a bijective correspondence between the geometric extensions of the theory MV and those of the theory Lu, a form of completeness and compactness for the infinitary theory Lu, three different levels of bi-interpretabilitity between the theory P and the theory L and a representation theorem for the finitely presentable objects of Chang's variety as finite products of perfect MV-algebras. We then show that the Morita-equivalence arising from Di Nola-Lettieri's equivalence is just one of a whole class of Morita¬equivalences that we establish between theories of local MV-algebras in proper varieties of MV-algebras and appropriate extensions of the theory of 1-groups. Furthermore, we generalize to this setting the representation results obtained in the case of Chang's variety

Повний текст джерелаIn this manuscript, we study Topological Quantum Field Theories built from a ribbon tensor category. We are particularly interested in the non-semisimple case. The main angle of this work is to make low-dimensional topology and higher algebra communicate. In one direction, explicit constructions from skein theory guide the higher algebra towards interesting examples. In the other, the cobordism hypothesis predicts new constructions. We construct 4-dimensional TQFTs from non-semisimple finite tensor categories satisfying some non-degeneracy conditions. This construction is joint work with Costantino, Geer and Patureau-Mirand. Unlike most other non-semisimple constructions, this TQFT is defined on every 4-cobordism. This feature was actually predictable from the cobordism hypothesis. Our construction is very explicit and we study some examples. Under some extra non-degeneracy conditions, we also provide an invariant of decorated 3-manifolds which is computed by our TQFT on a bounding 4-manifold. We relate this invariant to the renormalized Lyubashenko's invariants. These invariants provide the building block of DGGPR 3-dimensional TQFTs, which are non-semisimple variants of the well-known Witten-Reshetikhin-Turaev TQFTs. We argue that this point of view is very fruitful to understand these non-semisimple WRT theories and enables one to understand them as fully extended TQFTs. In the case where the ribbon category V is modular, the (3+1)-TQFT described above is invertible. It is also shown by Brochier, Jordan, Snyder and Safronov that the category V is invertible when thought of as an object of a 4-category of braided tensor categories. It is natural to expect that the TQFT Z associated to V by the cobordism hypothesis coincides with the one described above. Moreover, one should be able to recover DGGPR theories in a similar way, in a fully extended setting. More precisely, it is expected that there exists a fully extended boundary condition to Z which, when composed with Z on a bounding manifold, recovers DGGPR. We show that the unit inclusion, expected to be associated to this boundary condition under the cobordism hypothesis, is indeed sufficiently dualizable. Actually, we show that it is almost, but not entirely, 3-dualizable. We describe a so-called non-compact version of the cobordism hypothesis, and introduce the associated notion of non-compact dualizable object. Such objects give a partially defined, which we call non-compact, TQFT under the cobordism hypothesis. This explains precisely why the DGGPR theories are not defined on every 3-cobordim. We conjecture that the cobordism hypothesis applied on the unit inclusion and the modular category recovers, through a construction we describe, the non-semisimple WRT theories. On surfaces, the fully extended 4-TQFT is known to give factorization homology, which is described as modules over the so-called internal skein algebras by Brochier, Ben-Zvi and Jordan. We relate these internal skein algebras to Lê's stated skein algebras and study some of their properties. We give an explicit proof, and show that stated skein algebras do satisfy the universal property defining internal skein algebras. In particular, we argue that internal skein algebras are a very reasonable generalization of stated skein algebras. Moreover, we show gluing properties of internal skein algebras in any ribbon category, a result which is not known for other generalizations of stated skein algebras

Повний текст джерелаIn this thesis, we are concerned with some aspects of singular categories of unitalassociative k-algebras over a commutative ring k. First, we develop a Morita theory for singular categories. Analogous to the classical Morita theory, we propose a definition of singular equivalence of Morita type with level. This follows and generalizes a definition of stable equivalence of Morita type introduced by Michel Broué. A derived equivalence of standard type induces a singular equivalence of Morita type with level. Second, we study the Hom-space from A to A[i] in the singular category Dsg(AkAop) of the enveloping algebra AkAop, where A is an associative k-projective k-algebra and i is any integer. Recall that the i-th Hochschild cohomology group HHi(A,A) can be realized as the Hom-space from A to A[i] in the bounded derived category Db(A k Aop). From this motivation, we call HomDsg(AkAop)(A,A[i]) the i-th singular Hochschild cohomology group and denote this group by HHi sg(A,A). Analogous to the Hochschild cohomology ring HH_(A,A), we prove that there is a Gerstenhaber algebra structure on the singular Hochschild ring HH_sg(A,A) and provide an interpretation of the Lie bracket from the point of view of PROP theory. We also associate a cochain complex, which we call singular Hochschild cochain complex, C_sg(A,A) to the singular Hochschild cohomology. Thenwe study the higher algebraic structures (e.g. B1-algebra) on C_sg(A,A) and propose asingular version of the Deligne conjecture. Following Keller’s approach which was developed for derived equivalences, we establish the invariance of the Gerstenhaber algebra structure which we defined on the singular Hochschild cohomology under singular equivalence of Morita type with level. In this proof, we define the singular derived Picard group sgDPic(A) of an associative algebra A and develop what we call a singular infinitesimal deformation theory. Then we realize HH_sg(A,A) as the graded Lie algebra of the ‘graded algebraic group’ associated to sgDPic(A)

Повний текст джерелаThe aim of this PhD thesis is to study, from a functorial point of view, the mod 2 Morava K-theories of elementary abelian 2-groups. Namely, we study the covariant functors $V \mapsto K(n)^*(BV^{\sharp})$ for the prime p=2 and n a positive integer.The case n=1, which follows directly from the work of Atiyah on topological K-theory, gives us a coanalytic functor which contains no non-constant polynomial sub-functor. This is very different from the case n>1, where the above-mentioned functors are analytic.The theory of Henn-Lannes-Schwartz provides a correspondence between analytic functors and unstable modules over the Steenrod algebra. We determine the unstable module corresponding to the analytic functor $V \mapsto K(2)^*(BV^{\sharp})$, by studying the relation between this functor and the Hopf ring structure of the homology of the omega-spectrum associated to the theory K(2)
