Elliptic stable envelopes and hypertoric loop spaces.

This paper describes a relation between the elliptic stable envelopes of a hypertoric variety X and a distinguished K-theory class on the product of the loop hypertoric space L ~ X and its symplectic dual P X ! . This class intertwines the K-theoretic stable envelopes in a certain limit. Our results are suggestive of a possible categorification of elliptic stable envelopes. [ABSTRACT FROM AUTHOR]
