"Tensor and Matrix models: a one-night stand or a lifetime romance?"
Pablo Díaz Benito(Fields, Gravity & Strings, CTPU, Institute for Basic Science, Daejeon, KOREA)
We will see that the energy spectrum of free tensor models is organized by the Kronecker coefficients. It is known that the spectrum of free multimatrix models is organized by the Littlewood-Richardson numbers. Using recent results of group theory and combinatorics we derive a formula that relates those sets of numbers. The identity we obtain has a straightforward physics interpretation: there is a sector within tensor models whose states are in one-to-one correspondence with fluctuations of 1/2 BPS states in matrix models. This nontrivial fact is a strong hint for a close relation between both theories, which we will discuss
