It is pointed out that quantum states, in general, contain a new kind of orders that cannot be characterized by symmetry. A concept of quantum order is introduced to describe such orders. As two concrete examples, we discussed quantum orders in free fermion systems and in 2D spin1/2 systems. We generalize the Landau’s theory for the classical orders and introduce projective symmetry group and F...

Let p be prime. Let R be a discrete valuation ring of characteristic p with field of fractions K. Let C p denote the elementary abelian group of order p. In this paper we use Greither’s approach for classifying short exact sequences of finite R-group schemes to classify R-Hopf orders H in the group ring KC p , reproducing a result of Tossici. We then go further by providing an explicit descript...

Abstract Let G be a finite group and let ? ( ) denote the sum of element orders . It is well-known that maximum value on set groups order n , where positive integer, will occur at cyclic C For nilpotent groups, we prove natural generalization this result, obtained by replacing with relative to certain subgroup H
