Calculating Seshadri Constants


Seshadri constants - introduced by J-P. Demaille in 1990 - represent local information of the positivity of an ample line bundle on a given variety. These numbers, though easy to define, are hard to compute explicitly. In my talk I will first give a brief introduction to Seshadri constants, their definition, first properties and what is knows about them. Then I want to sketch some methods, how to calculate them, before finally discussing some examples.
