Short description: Theorem in algebra
In algebra, Posner's theorem states that given a prime polynomial identity algebra A with center Z, the ring [math]\displaystyle{ A \otimes_Z Z_{(0)} }[/math] is a central simple algebra over [math]\displaystyle{ Z_{(0)} }[/math], the field of fractions of Z.[1] It is named after Ed Posner.
