Title: An example which motivates why we need line bundles.

Speaker: Soumyadip Thandar

Abstract: This will be a motivational seminar about the importance of line
bundles( ie, vector bundles of rank 1). Giving a vector bundle of rank k
over some space is equivalent to give some data, such as an open cover for
the space, and a collection of maps from the intersections of these open
sets to Gl(k,C). We will first construct CP^n by gluing (n+1) copies of
C^n. We will then construct a special line bundle, called O(1), over CP^n ,
which possesses global sections. The main goal will be to prove that giving
a morphism from X to CP^n is equivalent to give a line bundle over X and
(n+1) sections which do not vanish simultaneously.
