Title: Cohomotopy groups in algebraic geometry and unimodular rows
Abstract: We will discuss the notion of cohomotopy groups in algebraic
geometry. Our main example and motivation will be the study of unimodular
rows, but we will also discuss other examples such as unimodular m x n
matrices and Euler class groups. The general context of this study is
motivic homotopy theory, but we will avoid technicalities and motivate the
constructions using classical topology.
