On the degrees of nondegenerated sections

A. L. Smirnov

St. Petersburg Department of Steklov Mathematical Institute of Russian Academy of Sciences

Abstract: The paper concerns vector bundles on the projective line over the ring of integers. We deal with bundles of rank 2 with the trivial generic fiber. We consider twistings of such a bundle with a certain degree. It is proved that for sufficiently high degrees there exist nonvaniching sections of corresponding twistings.

Key words and phrases: vector bundle, arithmetic surface, projective line, resultant, twist, section, nonvanishing.
