This workshop aims to bring together early career mathematicians and experts in algebraic geometry and combinatorics, working on the intersection of combinatorial Hodge and K-Theory. This is a highly active area of research with important connections to geometry, number theory, and discrete mathematics.

The workshop will be a mixture of two 4-hour lecture series by Omid Amini and Alex Fink, aimed at introducing the younger participants to the main subjects of the workshop, and research talks on the current status of the main themes.
