PBW--filtration over $\bz$ and compatible bases for $V_\bz(\la)$ in type $A_{n}$ and $C_{n}$

Evgeny Feigin, Ghislain Fourier, Peter Littelmann

We study the PBW-filtration on the highest weight representations $V(\la)$ of the Lie algebras of type $A_{n}$ and $C_{n}$ . This filtration is induced by the standard d…
