In this paper, we will show that for a smooth quasi-projective variety over $\C,$ and a regular function $W:X\to \C,$ the periodic cyclic homology of the DG category of matrix factorizations $MF(X,W)$ is identified (unde Riemann-Hilbert correspondence) with vanishing cohomology $H^{\bullet}(X^{an},\phi_W\C_X),$ with monodromy twisted by sign. Also, Hochschild homology is identified respectively with the hypercohomology of $(\Omega_X^{\bullet},dW\wedge).$ One can show that the image of the… 
Motivic Realizations of Matrix Factorizations and Vanishing Cycles
In this paper we prove a functorial and infinity-categorical version of Orlov's comparison theorem between the derived category $Sing(X,f)$ of singularities, and the derived category $MF(X,f)$ of
On categorical Donaldson-Thomas theory for local surfaces
We introduce the notion of $\mathbb{C}^{\ast}$-equivariant categorical Donaldson-Thomas theories for moduli spaces of stable sheaves on the total space of a canonical line bundle on a smooth
A Chern–Weil formula for the Chern character of a perfect curved module
Let $k$ be a field of characteristic 0 and $\mathcal{A}$ a curved $k$-algebra. We obtain a Chern-Weil-type formula for the Chern character of a perfect $\mathcal{A}$-module taking values in

The purpose of this work is to give a definition of a topological K-theory for dg-categories over $\mathbb{C}$ and to prove that the Chern character map from algebraic K-theory to periodic cyclic
Equivariant Hodge theory and noncommutative geometry
We develop a version of Hodge theory for a large class of smooth cohomologically proper quotient stacks $X/G$ analogous to Hodge theory for smooth projective schemes. We show that the noncommutative
Motivic Realizations of Singularity Categories and Vanishing Cycles
In this paper we establish a precise comparison between vanishing cycles and the singularity category of Landau-Ginzburg models over a complete discrete valuation ring. By using noncommutative
Coherent analogues of matrix factorizations and relative singularity categories
We define the triangulated category of relative singularities of a closed subscheme in a scheme. When the closed subscheme is a Cartier divisor, we consider matrix factorizations of the related
Exponentially Twisted Cyclic Homology
By a theorem of Bernhard Keller the de Rham cohomology of a smooth variety is isomorphic to the periodic cyclic homology of the differential graded category of perfect complexes on the variety. Both
Deformed dimensional reduction
Since its first use by Behrend, Bryan, and Szendr\H{o}i in the computation of motivic Donaldson-Thomas (DT) invariants of $\mathbb{A}_{\mathbb{C}}^3$, dimensional reduction has proved to be an


Étale descent for hochschild and cyclic homology
AbstractIfB is an étale extension of ak-algebraA, we prove for Hochschild homology thatHH*(B)≅HH*(A)⊗AB. For Galois descent with groupG there is a similar result for cyclic homology:HC*≅HC*(B)G if
such that m|ν=0 is the product on A. We will define a connection on the periodic cyclic bar complex of Aν for which the differential is covariant constant, thus inducing a connection on the periodic

Non-commutative Hodge structures: Towards matching categorical and geometric examples
The subject of the present work is the de Rham part of non-commutative Hodge structures on the periodic cyclic homology of differential graded algebras and categories. We discuss explicit formulas
Triangulated categories of singularities and D-branes in Landau-Ginzburg models
In spite of physics terms in the title, this paper is purely mathematical. Its purpose is to introduce triangulated categories related to singularities of algebraic varieties and establish a
Hochschild (co)homology of the second kind I
We define and study the Hochschild (co)homology of the second kind (known also as the Borel-Moore Hochschild homology and the compactly supported Hochschild cohomology) for curved DG-categories. An
Global matrix factorizations
We study matrix factorization and curved module categories for Landau-Ginzburg models (X,W) with X a smooth variety, extending parts of the work of Dyckerhoff. Following Positselski, we equip these
We relate the “Hodge filtration” of the cohomology of a complex algebraic variety X to the “Hodge decomposition” of its cyclic homology. If X is smooth and projective, HC (i) n (X) is the quotient of
Kontsevich's conjecture on an algebraic formula for vanishing cycles of local systems
For a local system and a function on a smooth complex algebraic variety, we give a proof of a conjecture of M. Kontsevich on a formula for the vanishing cycles using the twisted de Rham complex of
