Scientific activity >>  >> Seminar of Laboratory ¹5    Integrable Structures in Statistical and Field Models    The Seminar is held on Thursdays at 14:00, in room 615, IITP RAS. Head of the Seminar - Alexander Belavin, Alexander Zamolodchikov.     2015 December 29 (Tuesday), 1500, IITP RAS, room 615   Nikita Nekrasov (Simons Center of Geometry and Physics i IITP) Two solutions of the T-Q equation and gauge theory 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.
