SUMMARY:Bounded Negativity and Harbourne constants on Algebraic Surfaces
DESCRIPTION:Speaker: Aditya Subramaniam (TIFR)\n\nAbstract: \nStudy of Alge
 braic Surfaces is a classical subject. To understand surfaces\, it is natu
 ral to study the various properties of the curves on them. Even now\, ther
 e are several interesting conjectures about the properties of curves on su
 rfaces. One such conjecture is the Bounded Negativity Conjecture (BNC).\nL
 et X be a nonsingular projective surface. Bounded Negativity Conjecture (B
 NC) says that there is an integer b(X)\, depending only on X\, such that t
 he self-intersection C^2 is at least b(X) for every reduced curve C on X. 
 This conjecture is false in positive characteristic\, but it is open in ch
 aracteristic zero\, except in trivial cases. Harbourne constants were defi
 ned in an attempt to tackle this problem. I will introduce some of these i
 deas in this talk.\n
