A note on Franel numbers and

José Fernández Núñez, Wifredo García Fuertes, Askold M. Perelomov

We study weight multiplicities in tensor powers of the adjoint representation of and relate them to Franel numbers.

Euler's difference table and decomposition of tensor powers of adjoint representation of Lie algebra

A. M. Perelomov

By using of Euler's difference table, we obtain simple explicit formula for the decomposition of -th tensor power of adjoint representation of Lie algebra at $2 k \le{n+1}…

Euler's triangle and the decomposition of tensor powers of adjoint representation of Lie algebra

A. M. Perelomov

We consider the relation between Euler's trinomial problem and the problem of decomposition of tensor powers of adjoint representation of Lie algebra. By using this approach,…

Generating functions and multiplicity formulas: the case of rank two simple Lie algebras

Jose Fernandez Nunez, Wifredo Garcia Fuertes, Askold M. Perelomov

A procedure is described that makes use of the generating function of characters to obtain a new generating function giving the multiplicities of each weight in all the represe…
