Strict quantization of polynomial Poisson structures

Severin Barmeier, Philipp Schmitt

We show how combinatorial star products can be used to obtain strict deformation quantizations of polynomial Poisson structures on $R^{d}$ , generalizing known results for con…

Deformations of path algebras of quivers with relations

Severin Barmeier, Zhengfang Wang

Let $A = k Q / I$ be the path algebra of any finite quiver $Q$ modulo any two-sided ideal $I$ of relations and let $R$ be any reduction system satisfying the diamond condition…

Deformation-obstruction theory for diagrams of algebras and applications to geometry

Severin Barmeier, Yaël Frégier

Let $X$ be a smooth complex algebraic variety and let $Coh (X)$ denote its Abelian category of coherent sheaves. By the work of W. Lowen and M. Van den Bergh, it is…
