Howdy,

The TAMU Math Club will be meeting = next Monday, April 12th at 7:30pm over Zoom.

<= b>For students in Math 170, this counts as a math activity

Dr. Catherine Yan will be= presenting on the Lemma of Lindstrom-Gessel-Viennot and its applications i= n combinatorics.

The Lemma of Lin= dstrom-Gessel-Viennot is one of the most elegant=20 theorems in Enumerative Combinatorics, which reveals via involutions an=20 astounding connection between lattice paths and determinants. It was=20 originally proved by Lindstrom in 1973, but its combinatorial=20 significance was seen first and expounded by Gessel and Viennot.=C2=A0
I= n=20 this talk, we will start with the idea of involution/reflection in=20 combinatorial problems, introduce this lemma, and show various=20 applications in matrix identity, lattice path counting, and plane=20 partitions
