Abstract: In this talk, \(\mathbb{C}\) is the ground field. Let \(V\) be a natural representation of the Lie algebra \(\mathfrak{g}:=\mathfrak{gl}_\infty(\mathbb{C})\). Write \(V_*\) for a restricted dual of \(V\). The tensor representations of \(\mathfrak{g}\) are the \(\mathfrak{g}\)-modules of the form \(V^{\otimes(p,q)}:=V^{\otimes p}\otimes V_*^{\otimes q}\), where \(p\) and \(q\) are nonnegative integers. We shall describe the Jordan-Hölder constituents, socle filtrations, and indecomposable direct summands of such representations of \(\mathfrak{g}\). This talk is based on Tensor Representations of Classical Locally Finite Lie Algebras by I. Penkov and K. Styrkas.
