The result is a powerful theory with applications in many areas of mathematics. The book's first five chapters give an exposition of the theory of infinity-categories that emphasizes their role as a generalization of ordinary categories. Many of the fundamental ideas from classical category theory are generalized to the infinity-categorical setting, such as limits and colimits, adjoint functors, ind-objects and pro-objects, locally accessible and presentable categories, Grothendieck fibrations, presheaves, and Yoneda's lemma. A sixth chapter presents an infinity-categorical version of the theory of Grothendieck topoi, introducing the notion of an infinity-topos, an infinity-category that resembles the infinity-category of topological spaces in the sense that it satisfies certain axioms that codify some of the basic principles of algebraic topology.

In this first part, we introduce the notion of n-shifted symplectic structures (n-symplectic structures for short), a generalization of the notion of symplectic structures on smooth varieties and schemes, meaningful in the setting of derived Artin n-stacks (see To\"en and Vezzosi in Mem. Am. Math. Soc. 193, 2008 and To\"en in Proc. Symp. Pure Math. 80:435--487, 2009). We prove that classifying stacks of reductive groups, as well as the derived stack of perfect complexes, carry canonical 2-symplectic structures. Our main existence theorem states that for any derived Artin stack F equipped with an n-symplectic structure, the derived mapping stack Map(X,F) is equipped with a canonical (n-d)-symplectic structure as soon a X satisfies a Calabi-Yau condition in dimension d. These two results imply the existence of many examples of derived moduli stacks equipped with n-symplectic structures, such as the derived moduli of perfect complexes on Calabi-Yau varieties, or the derived moduli stack of perfect complexes of local systems on a compact and oriented topological manifold. We explain how the known symplectic structures on smooth moduli spaces of simple objects (e.g. simple sheaves on Calabi-Yau surfaces, or simple representations of {$\pi$}1 of compact Riemann surfaces) can be recovered from our results, and that they extend canonically as 0-symplectic structures outside of the smooth locus of simple objects. We also deduce new existence statements, such as the existence of a natural (-1)-symplectic structure (whose formal counterpart has been previously constructed in (Costello, arXiv:1111.4234, 2001) and (Costello and Gwilliam, 2011) on the derived mapping scheme Map(E,T{$\ast$}X), for E an elliptic curve and T{$\ast$}X is the total space of the cotangent bundle of a smooth scheme X. Canonical (-1)-symplectic structures are also shown to exist on Lagrangian intersections, on moduli of sheaves (or complexes of sheaves) on Calabi-Yau 3-folds, and on moduli of representations of {$\pi$}1 of compact topological 3-manifolds. More generally, the moduli sheaves on higher dimensional varieties are shown to carry canonical shifted symplectic structures (with a shift depending on the dimension).}, langid = {english}, file = {/home/alexk/Zotero/storage/CTXXH53Z/Pantev et al. - 2013 - Shifted symplectic structures.pdf} } @article{pantev2021, title = {Poisson {{Geometry}} of the {{Moduli}} of {{Local Systems}} on {{Smooth Varieties}}}, author = {Pantev, Tony and To{\"e}n, Bertrand}, year = 2021, month = oct, journal = {Publications of the Research Institute for Mathematical Sciences}, volume = {57}, number = {3}, pages = {959--991}, issn = {0034-5318}, doi = {10.4171/prims/57-3-8}, urldate = {2022-10-30}, abstract = {We study the moduli of \$G\$-local systems on smooth but not necessarily proper complex algebraic varieties.

If A is a smooth commutative k-algebra and k has characteristic 0, we show that two objects, S1{$\otimes$}A and {$\epsilon$}(A), determine one another, functorially in A. The object S1{$\otimes$}A is the S1-equivariant simplicial k-algebra obtained by tensoring A by the simplicial group S1 :=B{$\mathbb{Z}$}, while the object {$\epsilon$}(A)is the de Rham algebra of A, endowed with the de Rham differential, and viewed as a {$\epsilon$}-dg-algebra (see the main text). We define an equivalence {$\varphi$} between the homotopy theory of simplicial commutative S1-equivariant k-algebras and the homotopy theory of {$\epsilon$}-dg-algebras, and we show the existence of a functorial equivalence {$\phi$}(S1 {$\otimes$}A){$\sim\epsilon$}(A) . We deduce from this the comparison mentioned above, identifying the S1-equivariant functions on the derived loop space LX of a smooth k-scheme X with the algebraic de Rham cohomology of~X/k.
