Description:
Speaker: Jean Fasel, Université de Grenoble I, Grenoble, France Date/Time: 1 October 2021, 6:30pm IST/ 1:00pm GMT / 9:00am EDT (joining time 6:15pm IST) Zoom link: https://univ-grenoble-alpes-fr.zoom.us/j/99339034373?pwd=MlIybEJYWjVSQnlqS1NWSDRpSk5wUT09 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.
