The Riemann-Roch theory is the most important tool for connecting analytic, algebraic and topological properties of manifolds. This monograph concentrates on the complex dimension 2, ie on complex algebraic surfaces. The aim of this book is to introduce a new kind of rational discrete invariants into surface theory and to demonstrate their power for solving current problems.
