FELDER, G. and VESELOV, A.P., 2009. Baker-Akhiezer function as iterated residue and Selberg-type integral . Glasgow Mathematical Journal, 51 (A), pp. 59 - 73.
A simple integral formula as an iterated residue is presented for the Baker–Akhiezer function related to An-type root system in both the rational and trigonometric cases. We present also a formula for the Baker–Akhiezer function as a Selberg-type integral and generalise it to the deformed An,1-case. These formulas can be interpreted as new cases of explicit evaluation of Selberg-type integrals.
