Title: Introduction to association schemes

Abstract: The theory of association schemes is an important toolbox for algebraic graph theory. We will give an introduction to association scheme, distance regular graphs and the clique-coclique bound.

Title: A unified Erd\H os-P\'osa theorem for constrained cycles

Title: On some polytopes contained in the 0,1 hypercube that have a small
chvatal rank

Title: The perfect matching polytope and solid graphs

Title: Hopf algebras, colorings and simplicial complexes

Title: Strongly regular subconstituents of strongly regular graphs

Title: The replication conjecture II

Abstract: In 1993, Conforti and Cornuejols conjectured that replicating the vertex of a clutter preserves the packing property. I will present some tools that will be helpful in tackling this conjecture. The upshot is to take advantage of the fact that clutters with the packing property exclude delta minors, as well as some other small minors.
