Periods, Shafarevich Maps and Applications - Nodal Surfaces and Coding Theory

Explore a comprehensive lecture on the application of period maps theory to K3 surfaces, focusing on the Torelli theorem and its implications for nodal K3 surfaces. Delve into the classification of irreducible components of polarized nodal K3 varieties and their incidence relations. Examine the connection between these components and isomorphism classes of associated binary codes. Investigate the concept of K3 codes and the conditions for primitive embedding of related lattices in the K3 lattice. Learn about the shortening of codes and its correspondence to partial smoothing, with specific examples from quartic surfaces. If time allows, gain insights into surfaces of degree 5 and 6 in 3-space, broadening your understanding of algebraic geometry and coding theory applications in this advanced mathematical exploration.
