On the Stability of ,,,This brief note outlines some of the author’s results appearing in . Suppose E is a vector bundle over a smooth irreducible projective curve C of genus g, and assume that global sections generate E. The natural evaluation map gives rise to a sequence of vector bundles: ..

Rigid Sheaves on Surfaces,Sheaves on surfaces can be divided into two main classes: sheaves with deformations and sheaves without deformations. Among the latter there are sheaves that have niether global nor infinitesimal deformations, in other words, the group Ext.(.) is trivial. These sheaves, called rigid, are the subject of the present paper.

On the Brauer Group of Real Algebraic Surfaces,In the paper of R. Sujatha and the author , the Brauer group of a real Enriques surface was studied. Here we continue the study of Brauer group with the remark that most of the results of these paper generally valid for an arbitrary smooth projective real algebraic surface.
