Group Actions on Vector Bundles on the Projective Plane
We study the action of the group of automorphisms of the projective plane on the Maruyama scheme of sheaves MP 2(r, c1,c2) of rank r and Chern classes c1 = 0 and c2 = n and obtain sufficient conditions for unstability in the sense of Mumford’s geometric invariant theory. The conditions are in terms of the splitting behaviour of sheaves when restricted to lines in the projective plane. A very st...
متن کاملLinear Spaces and Partitioning the Projective Plane
The aim of this paper is to settle a question about the partitioning of the projective plane by lines except for a small set. Suppose that Q is a set of points in the projective plane of order n and 6 is a set of lines that partitions the complement of Q. If Q has at most 2n&1 points and P has less than n+1+n lines, then these lines are concurrent. An example is given which shows that the condi...

15 صفحه اولDynamics of Singular Holomorphic Foliations on the Complex Projective Plane
This manuscript is a revised version of my Master’s thesis which was originally written in 1992 and was presented to the Mathematics Department of University of Tehran. My initial goal was to give, in a language accessible to non-experts, highlights of the 1978 influential paper of Il’yashenko on singular holomorphic foliations on CP [I3], providing short, self-contained proofs. Parts of the ex...
