Linear systems on a special rational surface
We study the Hilbert series of a family of ideals Jφ generated by powers of linear forms in K[x1, . . . , xn]. Using the results of Emsalem-Iarrobino, we formulate this as a question about fatpoints in P. In the three variable case this is equivalent to studying the dimension of a linear system on a blow up of P. The ideals that arise have the points in very special position, but because there ...
متن کاملLinear series on a special rational surface
We study a result of Postnikov-Shapiro concerning the Hilbert series of a family of ideals Jφ generated by powers of linear forms in k[x1, . . . , xn]. Using the results of Emsalem-Iarrobino, we formulate this as a problem about fatpoints in P. In the three variable case this is equivalent to studying the dimension of a linear series on a blow up of P. The ideals that arise have the points in v...
متن کاملTHE RATIONAL CHARACTER TABLE OF SPECIAL LINEAR GROUPS
In this paper we will give the character table of the irreducible rational representations of G=SL (2, q) where q= , p prime, n>O, by using the character table and the Schur indices of SL(2,q).
متن کاملLinear Systems of Rational Curves on Rational Surfaces
Given a curve C on a projective nonsingular rational surface S, over an algebraically closed field of characteristic zero, we are interested in the set ΩC of linear systems L on S satisfying C ∈ L, dimL > 1, and the general member of L is a rational curve. The main result of the paper gives a complete description of ΩC and, in particular, characterizes the curves C for which ΩC is non empty. 20...
