Centers of skew polynomial rings

Waldo Arriagada Hugo Ramírez

Abstrak

We determine the center C(K[x;?]) of the ring of skew polynomials K[x;?], where K is a field and ? is a non-zero derivation over K. We prove that C(K[x;?]) = ker ?, if ? is transcendental over K. On the contrary, if ? is algebraic over K, then C(K[x;?])=(ker ?)[?(x)]. The term ?(x) is the minimal polynomial of ? over K.
