AbstractLet k(x~,..., x,~)/k be a finitely generated field extension, and gl,... ,gr e k(g). For k ( x l , . . . ,x,~)/k(g:,... ,g~) being separably generated (which in particular includes the case char(k) = 0) we give a method to compute the transcendence degree and a separating transcendence basis of this extension by means of simple linear algebra techniques.
