*Junior Kolloquium*

*Univ.-Prof. Dr. Mihai Ciucu: “Combinatorial aspects of the dimer model”*

**

Abstract: The dimer model was phrased by physicists in the 1930's as a theoretical model for the adsorption of a liquid through the face of a crystal. Since then this model has turned out to be relevant in several other connections. One of them is the emergence of two dimensional electrostatics from the interaction of holes in dimer systems on bipartite planar lattices. This talk presents how I was led to the latter starting from a generalization of MacMahon's boxed plane partitions theorem.

*Mathematisches Kolloquium*

*Univ.-Prof. Dr. Mihai Ciucu: “Gaps in dimer systems and beyond”*

**

Abstract:The prototypical example of interaction of gaps in dimer coverings was formulated by Fisher and Stephenson in 1963. Suppose we have a huge $2n\times 2n$ chessboard, and we remove a white and a black unit square from around its center. How does the number of domino tilings of the leftover board change, as the two removed unit squares move around the center of the board?

  

We extend the set-up to dimer coverings on planar lattices, and focus on the interaction of a finite number of gaps in the dimer covering. A number of qualitatively different behaviors arise in this way. These include two-dimensional electrostatics, for bipartite lattices with critical weighting, and a radically different interaction for critical non-bipartite lattices. Effects of the boundary of lattice graphs will also be considered, as well as connections to some classical problems in enumerative combinatorics involving plane partitions.

  

Throughout the discussion there is a helpful interplay between combinatorics and physical intuition. The talk is intended for a

general audience.
