Summary: This article discusses the relationship between commutative algebra and Poisson ideals, as well as the concepts of Lie brackets and Lie-Rinehart pairs. Furthermore, the concept of cotangent complex and L-infinity-algebroids are introduced, along with their relationships.

Summary: This study proves that the Poisson cohomology theory of a Poisson algebra introduced by Flato et al. (1995) can be described by a specific derived functor. It also demonstrates the equivalence between (generalized) deformation quantization and formal deformation for Poisson algebras under certain mild conditions. Finally, a long exact sequence is constructed, and it is used to calculate the Poisson cohomology groups through the Yoneda-extension groups of certain quasi-Poisson modules and the Lie algebra cohomology groups.

Summary: This article presents how combinatorial star products can be used to achieve strict deformation quantizations of polynomial Poisson structures on R^d, extending known results for constant and linear Poisson structures to polynomial Poisson structures of arbitrary degree. Several examples of nonlinear Poisson structures are given, along with explicit formal star products that allow the evaluation of the deformation parameter to any real value of (h) over bar, resulting in strict quantizations on the space of analytic functions on R^d with infinite radius of convergence. The article also addresses further questions such as the continuity of the classical limit (h) over bar -> 0, compatibility with *-involutions, and the existence of positive linear functionals.

Summary: We study a family of topological twists of a supersymmetric mechanics with a Kahler target, and find that it exhibits a Batalin-Vilkovisky quantization. Based on this observation, we propose a general scheme for the Hilbert space of states after a topological twist, using the cohomology of a certain perverse sheaf. We provide several examples of resulting Hilbert spaces, including the categorified Donaldson-Thomas invariants, Haydys-Witten theory, and the 3-dimensional A-model.

Summary: In this paper, we extend the notion of Morita equivalence of Poisson manifolds to formal Poisson structures and provide a complete description of Morita equivalent formal Poisson structures deforming the zero structure. Our results connect the notions of Morita equivalence in Poisson geometry and noncommutative algebra via deformation quantization.

Summary: Nambu quantum mechanics, proposed in 2002, is a deformation of canonical quantum mechanics that modifies only the time-evolution of energy eigenstates phases. The theory's effect on oscillation phenomena is discussed, and a bound on the deformation parameters is placed using data on the atmospheric neutrino mixing angle theta(23).

Summary: In this work, we provide a detailed computation of weights of Kontsevich graphs arising from connection and curvature terms in the context of globalization, focusing on symplectic manifolds. We demonstrate how the weights of curvature graphs can be explicitly expressed using hypergeometric functions and a simpler formula in combination with the weights of its underlying connection graphs. Additionally, we explore the case of a cotangent bundle, leading to a significant simplification of the curvature expression.

Summary: We present a category that includes all quantizations of Poisson algebras. This category allows for the unified treatment of different quantizations for all Poisson algebras and introduces a new classical limit formulation. We define equivalence of quantizations using this category and investigate the conditions for which two quantizations are equivalent. Additionally, we define two types of classical limits within the context of category theory and discuss the inverse problem of determining the classical limit from a noncommutative Lie algebra.

Summary: The classical limits of quantum groups lead to multiplicative Poisson structures such as Poisson-Lie and quasi-Poisson structures, which are related to the concept of a shifted Poisson structure providing a framework for understanding classical (dynamical) r-matrices, quasi-Poisson groupoids, etc. A notion of a symplectic realization of shifted Poisson structures is proposed, with Manin pairs and Manin triples serving as examples of such realizations.

Summary: In this study, we utilize the Fedosov connections constructed in [7] to investigate smooth functions on a Kahler manifold X. We discover a subsheaf that allows for non-formal deformation quantization, and we prove that when X is prequantizable and the Fedosov connection satisfies an integrality condition, this subsheaf can be quantized into a sheaf of twisted differential operators (TDO) which is isomorphic to the prequantum line bundle. We also demonstrate that examples of such quantizable functions are obtained from images of quantum moment maps.

Summary: We investigate quantization schemes on a complex manifold and their relation to several interesting structures. We first construct Fedosov's star products as quantizations of Kapranov's L-infinity-algebra structure on a complex manifold X. Then, we explore the Batalin-Vilkovisky (BV) quantizations associated with these star products. Notably, all the BV quantizations are one-loop exact, implying that the Feynman weights associated with graphs with two or more loops all vanish. This leads to a concise cochain level formula in de Rham cohomology for the algebraic index.

Summary: Weakly associative algebras generalize associative algebras and help extend the class of formal deformations of associative commutative algebras. The algebraic study of weakly associative algebras, especially the homology of free algebras with one generator, is interesting and significant.
