#### Math Physics Seminar, Saidakhmat Lakaev, "Threshold effects of the two and three-particle Schroedinger operators on lattices"

Efimov's effect for a system of three particles moving on three-dimensional lattice and interacting via pairwise short-range potentials is studied. The following new results will be presented:

(i). Infinitude of the number of eigenvalues (Efimov's effect) for zero quasi-momentum, and its finiteness for non-zero values of the quasi-momentum. (ii).The corresponding asymptotics for the number of eigenvalues.
