Abstract

In this article, we find a q-analogue for Fomin’s formulas. The original Fomin’s formulas relate determinants of random walk excursion kernels to loop-erased random walk partition functions, and our formulas analogously relate conformal block functions of conformal field theories to pure partition functions of multiple SLE random curves. We also provide a construction of the conformal block functions by a method based on a quantum group, the q-deformation of sl2. The construction both highlights the representation theoretic origin of conformal block functions and explains the appearance of q-combinatorial formulas.
