Abstract
Linear quiver N = 2 4d gauge theory in Ω background is considered. It is proved that the partition function in a simple way is related to the expectation values of Baxter’s Q operator (at specific discrete values of the spectral parameter) in the gauge theory with the first node removed. Explicit expressions for the VEV of the Q operator in terms of generalized Apell’s functions are found.
