Abstract: Seshadri constants of line bundles on projective varieties were defined by J-P. Demailly in 1990, motivated by an ampleness criterion of C. S. Seshadri. They are a measure of local positivity of line bundles and have interesting connections to different areas in mathematics. We will discuss some important questions that drive research on Seshadri constants. We will also discuss their relationship with Waldschmidt constants which are invariants attached to homogeneous ideals in polynomial rings.
