Abstract

In 1981, Thompson proved that, if is any integer and is any finite subgroup of, then has a semi-invariant of degree at most. He conjectured that, in fact, there is a universal constant such that for any and any finite subgroup <![CDATA[G, has a semi-invariant of degree at most. This conjecture would imply that the-invariant, as introduced by Tian in 1987, is at most. We prove Thompson's conjecture in this paper.
