The del-bar-operator on algebraic curves

Bruening, J.; Peyerimhoff, N.; Schroeder, H.

Abstract

For a singular algebraic curve we show that all closed extensions of del-bar are Fredholm, and we give a general index formula. In particular, we prove a modified version of a conjecture due to Mac Pherson.
