چکیده

Theorem. 1.1 Let X be a projective geometrically reduced and irreducible scheme over a field k of (arbitrary) characteristic p and let M , L be line bundles on X with L ample. If p is positive then suppose further that X is smooth in codimension one. For fixed m ≥ 0 there exists d0 = d0(m), depending also on X,L,M, such that for any d ≥ d0 and any generic union Z of (fat) points of multiplicity ≤ m the canonical map H(X,M ⊗ L) −→ H(Z,OZ ⊗ M ⊗ L )

Fixed points for E-asymptotic contractions and Boyd-Wong type E-contractions in uniform spaces

In this paper we discuss on the fixed points of asymptotic contractions and Boyd-Wong type contractions in uniform spaces equipped with an E-distance. A new version ofKirk's fixed point theorem is given for asymptotic contractions and Boyd-Wong type contractions is investigated in uniform spaces.

$G$-asymptotic contractions in metric spaces with a graph and fixed point results

In this paper, we discuss the existence and uniqueness of fixed points for $G$-asymptotic contractions in metric spaces endowed with a graph. The result given here is a new version of Kirk's fixed point theorem for asymptotic contractions in metric spaces endowed with a graph. The given result here is a generalization of fixed point theorem for asymptotic contraction from metric s paces to metr...

Infinite product representation of solution of indefinite SturmLiouville problem

In this paper, we investigate infinite product representation of the solution of a Sturm- Liouville equation with an indefinite weight function which has two zeros and/or singularities in a finite interval. First, by using of the asymptotic estimates provided in [W. Eberhard, G. Freiling, K. Wilcken-Stoeber, Indefinite eigenvalue problems with several singular points and turning points, Math. N...
