The homotopy type of toric arrangements
Hyperplane arrangements toric arrangements CW-complex Salvetti complex
2010/12/8
A toric arrangement is a finite set of hypersurfaces in a complex torus,every hypersurface being the kernel of a character. In the present paper we build a CW-complex homotopy equivalent to the arrang...
In this paper, we study algebras of tame acyclic cluster type. These are algebras of global dimension at most 2 whose generalized cluster category is equivalent to a cluster category of an acyclic qui...
Rickart-type Annihilator Conditions on Formal Power Series
Annihilator conditions Nearrings Skew power series Baer rings a-rigid rings Rickart rings
2010/2/25
Let R be an a-rigid ring and R0[[x;a]] be the nearring of a formal skew power series in which addition and substitution are used as operations. It is shown that R is Rickart and any countable family o...
