## Abstract

We study plane partitions satisfying condition a_{n} _{+} _{1} _{,} _{m} _{+} _{1}= 0 (this condition is called “pit”) and asymptotic conditions along three coordinate axes. We find the formulas for generating function of such plane partitions. Such plane partitions label the basis vectors in certain representations of quantum toroidal gl_{1} algebra, therefore our formulas can be interpreted as the characters of these representations. The resulting formulas resemble formulas for characters of tensor representations of Lie superalgebra gl_{m} _{|} _{n}. We discuss representation theoretic interpretation of our formulas using q-deformed W-algebra gl_{m} _{|} _{n}.
