In this paper we show that the ring $R$ and its action on $L$ are 0-interpretable in $L$, viewed as a ring with the standard ring language $+, \\cdot,0$. Furthermore, if $R$ has characteristic zero then we prove that the elementary theory $Th(L)$ of $L$ in the standard ring language is undecidable. To do so we show that the arithmetic ${\\bf N} = \\langle{\\bf N}, +,\\cdot,0 \\rangle$ is 0-interpretable in $L$. This implies that the theory of $Th(L)$ has the independence property.
