Free field realizations of the Date-Jimbo-Kashiwara-Miwa algebra (1309.7316v1)
Published 27 Sep 2013 in math.RT
Abstract: We use the description of the universal central extension of the DJKM algebra $\mathfrak{sl}(2, R)$ where $ R=\mathbb C[t,t{-1},u\,|\,u2=t4-2ct2+1 ]$ given in earlier work to construct realizations of the DJKM algebra in terms of sums of partial differential operators.
