Multi-point Seshadri Constants on Surfaces

Alapan Mukhopadhyay
Chennai Mathematical Institute.


Seshadri constants are fundamental and diversely appearing invariants in Algebraic Geometry. Although there is a good conjectural picture of values of Seshadri constants of ample line bundles on surfaces (non-singular, complex, projective), these invariants are not easily computable. In this talk, we will discuss some computational aspects of multi-point Seshadri constants on surfaces.

First, we will give an overview of some current and past research works on this topic. Then we will present some new results obtained in a joint work with Krishna Hanumanthu.
