Abstract
Let be an -local field with an -th residue field , for some integer , and let be a field extension of transcendence degree trd. This paper shows that if is a field of finite Diophantine dimension (for example, a finitely-generated extension of a finite or a pseudo-algebraically closed perfect field ), then the absolute Brauer -dimension abrd of is finite, for every prime number . Thus it turns out that if is an associative locally finite-dimensional (abbr., LFD) central division -algebra, then it is a normally locally finite algebra over , that is, every nonempty finite subset of is contained in a finite-dimensional central -subalgebra of .
