Abstract

New graded modules for the current algebra of sln are introduced. Relating these modules to the fusion product of simple sln-modules and local Weyl modules of truncated current algebras shows their expected impact on several outstanding conjectures. We fur- ther generalize results on PBW filtrations of simple sln-modules and use them to provide decomposition formulas for these new modules in important cases.
