| Description |
Normal functions are certain transcendental objects introduced by Poincare in a 1910 paper and later used by Lefschetz to prove the Hodge conjecture for algebraic surfaces, i.e., the Lefschetz(1.1) theorem. The key to Lefschetz's proof, whichis already present in Poincare's work, is that the normal functions that arise from Hodge classes on algebraic surfaces are essentially algebraic objects. ........contd....... I will discuss normal functions ending with a recent theorem coming from joint work with G.Pearlstein (also obtained independently by C. Schnell) showing that the zero locus of an admissible normal function is algebraic. |
