Два решения T-Q уравнения и калибровочная теория

The celebrated T-Q equation, in the A_{1} case, is a second order linear difference equation on the eigenvalues of the Baxter Q-operator. It has, accordingly, two linearly independent (over the quasi-constants) solutions. I will present the gauge theoretic construction of these solutions, using the recently proposed gauge origami models, which will be also reviewed.
