ABSTRACT:

Invariants of combinatorial structures can be very useful tools that
capture some specific characteristics, and repackage them in a
meaningful way. For example, the famous Tutte polynomial of a matroid
or graph tracks the rank statistics of its submatroids, which has many
applications, and relations like contraction-deletion establish a very
close connection between the algebraic structure of the invariant
(e.g. Tutte polynomials) and the actual matroid itself.
