Abstract
For a ring with an automorphism , an -additive mapping is called a skew -derivation with respect to if it is always a -derivation of for each argument. Namely, it is always a -derivation of for the argument being left once arguments are fixed by elements in . In this short note, starting from Bre\v{s}ar Theorems, we prove that a skew -derivation () on a semiprime ring must map into the center of .
