Picard and Lefschetz numbers of real algebraic surfaces
V. A. Krasnov P. G. Demidov Yaroslavl State University
Abstract:
Two Picard numbers and two Lefschetz numbers are defined for a real algebraic surface. They are similar to the Picard number and the Lefschetz number of a complex algebraic surface. For these numbers, some estimates and relations in the form of inequalities are proved.
