The Grothendieck Riemann Roch Theorem is widely regarded as the defining work in Grothendieck's theory of schemes. The theorem has influenced many areas of mathematics, most notably algebraic geometry and number theory. The main aim of the workshop is to study the Grothendieck Riemann Roch theorem for smooth quasi projective schemes.

In a series of lectures, comprising five modules (each module consists of five lectures with each lecture of duration 1.5 hour), we discuss the following topics in detail: The Riemann Roch theorems for curves and complex algebraic varieties, Chow groups, Intersection theory, Chern classes, and Todd Classes.

Furthermore, we have a series of survey talks on the complex analytic aspects of the Grothendieck Riemann Roch theorem, and its influences on other areas of mathematics.

The workshop is designed for graduate students working in Algebraic Geometry, and young postdoctoral fellows who work in related areas.
