Simple skew polynomial ringsMichael G. VoskoglouInstitute of Technological Education, Patras, GreceAbstract: We treat two questions. First we give the general conditions for the existence of skew polynomial rings in finitely many variables over a given ring $R$ (special cases of such rings are well, known, typifield by the $n$th Weyl Algebras) and second we obtain the necesary and sufficient conditions for the simplicity of such rings. \par Note that Amitsur [1] obtained conditions under which an Ore extension $R[x,d]$ over a simple ring $R$ is simple, while more recently Jordan [6] obtained such conditions if $R$ is $d$simple.
