Scott Fitzgerald at the background of the patriarchal society, Daisy stands for a traditional oppressed woman whereas Jordan represents a new female image in pursuit of freedom and independence. Simultaneously, their images also reveal an inspiring implication for women who want to obtain independence and freedom, only when women break the shackles of patriarchal ideology and gain the independence of economy by unremitting efforts can they completely enjoy the independence of mind as well as the right that they deserve.展开更多

This time we study the algebra property of the classes S_(p,q)~rB(R^d) with respect to pointwise multiplication. In addition, if p≤q, we are able to describe the space of all pointwise multipliers for S_(p,q)~rB(R^d).展开更多
