Induced modules and central character quotients for Takiff $\mathfrak{sl}_{2}$

Abstract: We construct a large new family of simple modules over Takiff $\mathfrak{sl}{2}$. We prove that the quotient of the universal enveloping algebra of the Takiff Lie algebra for $\mathfrak{sl}{2}$ by the ideal generated by a non-trivial central character is a simple algebra. In the case of the trivial central character, we show that the corresponding ideal is primitive by explicitly constructing a simple module whose annihilator coincides with that ideal. Together with the annihilators of simple $\mathfrak{sl}_{2}$-modules, we expect that the above ideals exhaust all primitive ideal.
