Title: Seshadri Constant on Surfaces.
Abstract: Seshadri constant is a tool to study/quantify the positivity of
a line bundle on a projective variety. It was defined by Demailly in late
80s to study the Fujita conjecture, but afterwards it arose as an
independent area or research with computing and bounding the constant as
some of the main topics of research. In this talk we will see some of such
results obtained on Hyperelliptic surfaces and on surfaces of general
type.
