Luca Rizzi 氏 (Udine)
Adjoint forms on algebraic varieties (English)
[ 講演概要 ]
The so called adjoint theory was introduced by A. Collino and G.P. Pirola in the case of smooth algebraic curves and then generalized by G.P. Pirola and F. Zucconi in the case of smooth algebraic varieties of arbitrary dimension.
The main idea of this theory is to study particular differential forms, called adjoint forms, on an algebraic variety to obtain information on the infinitesimal deformations of the variety itself.
The natural context for the application of this theory is given by Torelli-type problems, in particular infinitesimal Torelli problems.
