The Ding-Iohara algebra is a quantum algebra arising from the free field
realization of the Macdonald operator. Starting from the elliptic kernel
function introduced by Komori, Noumi and Shiraishi, we can define an elliptic
analog of the Ding-Iohara algebra. The free field realization of the elliptic
Macdonald operator is also constructed.Comment: 42 page
