Popis: Irreducible representations of the plactic monoid M of rank four are studied. Certain concrete families of simple modules over the plactic algebra K [ M ] over a field K are constructed. It is shown that the Jacobson radical J ( K [ M ] ) of K [ M ] is nilpotent. Moreover, the congruence ρ on M determined by J ( K [ M ] ) coincides with the intersection of the congruences determined by the primitive ideals of K [ M ] corresponding to the constructed simple modules. In particular, M / ρ is a subdirect product of the images of M in the corresponding endomorphism algebras.
