We introduce a formal $$\hbar $$ -differential operator $$\Delta $$ that generates higher Koszul brackets on the algebra of (pseudo)differential forms on a $$P_{\infty }$$ -manifold. Such an operator was first mentioned by Khudaverdian and Voronov in arXiv:1808.10049. (This operator is an analogue of the Koszul–Brylinski boundary operator $$\partial _P$$ which defines Poisson homology for an ordinary Poisson structure.) Here, we introduce $$\Delta =\Delta _P$$ by a different method and… 
Higher Koszul Brackets on the Cotangent Complex
Let $A=\boldsymbol{k}[x_1,x_2,\dots ,x_n]/I$ be a commutative algebra where $\boldsymbol{k}$ is a field, $\operatorname{char}(\boldsymbol{k})=0$, and $I\subseteq S:=\boldsymbol{k}[x_1,x_2,\dots ,
Quantization of (-1)-Shifted Derived Poisson Manifolds
. We inv estigate the quantization problem of ( − 1) -shifted derived Poisson manifolds in terms of BV ∞ -operators on the space of Berezinian half-densities. We prove that quantizing such a ( − 1)

Thick morphisms, higher Koszul brackets, and $L_{\infty}$-algebroids
It is a classical fact in Poisson geometry that the cotangent bundle of a Poisson manifold has the structure of a Lie algebroid. Manifestations of this structure are the Lichnerowicz differential on

We analyze geometry of the second order differential operators, having in mind applications to Batalin--Vilkovisky formalism in quantum field theory. As we show, an exhaustive picture can be obtained

We recall the main facts about the odd Laplacian acting on half-densities on an odd symplectic manifold and discuss a homological interpretation for it suggested recently by P. {\v{S}}evera. We study

We survey the many instances of derived bracket construction in differential geometry, Lie algebroid and Courant algebroid theories, and their properties. We recall and compare the constructions of

We define graded manifolds as a version of supermanifolds endowed with an extra Z-grading in the structure sheaf, called weight (not linked with parity). Examples are ordinary supermanifolds, vector

Double Lie algebroids were discovered by Kirill Mackenzie from the study of double Lie groupoids and were defined in terms of rather complicated conditions making use of duality theory for Lie
