Free field realizations of the Date-Jimbo-Kashiwara-Miwa algebra
We use the description of the universal central extension of the DJKM algebra
where
given in earlier work to construct realizations of the DJKM algebra in terms of
sums of partial differential operators.Comment: arXiv admin note: substantial text overlap with arXiv:1303.697
Free Field Representation of Quantum Affine Algebra U_q(\hat{sl}_2)
A Fock representation of the quantum affine algebra U_q(\widehat{\sl}_2) is
constructed by three bosonic fields for an arbitrary level with the help of the
Drinfeld realization.Comment: 11 page
