 A Note on Algebras that are Sums of Two Subalgebras We study an associative algebra $A$ over an arbitrary field, that is a sum of two subalgebras $B$ and $C$ (i.e. $A=B+C$). We show that if $B$ is a right or left Artinian $PI$ algebra and $C$ is a $PI$ algebra, then $A$ is a $PI$ algebra. Additionally we generalize this result for semiprime algebras $A$. Consider the class of all semisimple finite dimensional algebras $A=B+C$ for some subalgebras $B$ and $C$ which satisfy given polynomial identities $f=0$ and $g=0$, respectively. We prove that all algebras in this class satisfy a common polynomial identity. Keywords:rings with polynomial identities, prime ringsCategories:16N40, 16R10, , 16S36, 16W60, 16R20

 Jacobson Radicals of Skew Polynomial Rings of Derivation Type We provide necessary and sufficient conditions for a skew polynomial ring of derivation type to be semiprimitive, when the base ring has no nonzero nil ideals. This extends existing results on the Jacobson radical of skew polynomial rings of derivation type. Keywords:skew polynomial rings, Jacobson radical, derivationCategories:16S36, 16N20
