Schur relations

In the second section, we derive the Schur relations in the case where the characteristic of the underlying base field does not divide any of the integers s with s G S and is algebraically closed. 

In the case where S is thin, the equations of the following theorem are known as Schur relations. 

Professor Schur also made me aware of a consideration by Frobenius which is closely related to the argument given in Sec. 19. 

In Section 6.4, we use previously obtained results about Schur groups in order to establish a recognition theorem for certain schemes of finite valency all elements of which have valency at most 2. The theorem is related to one of the most significant results in finite group theory, to George Glauberman s Z -Theorem. 

How does this example relate to Schur s lemma Well, it is easy to check that translation of the functional variable which gives us our representation...
