Abstract

We show that many tame modules of the quantum toroidal gl2\mathfrak{gl}_2 algebra can be explicitly constructed in a purely combinatorial way using the theory of qq-characters. The examples include families of evaluation modules obtained from analytic continuation and automorphism twists of Verma modules of the quantum affine gl2\mathfrak{gl}_2 algebra. The combinatorial bases in the modules are labeled by colored plane partitions with various properties.
