This not only need to study the origins of the traditional central Idea of the culture,but also need to study the course of the development of the modern society of china,still need to analyze the personality of the returned students of China early stage.
In our paper [KR] we began a systematic study of representations of the universal central extension[InlineEquation not available: see fulltext.] of the Lie algebra of differential operators on the circle.
In the present paper we study the remaing nontrivial case, that of a negative central charge-N.
We consider some remarkable central elements of the universal enveloping algebraU(gl(n)) which we call quantum immanants.
We modify the Hochschild φ-map to construct central extensions of a restricted Lie algebra.
Such central extension gives rise to a goup scheme that leads to a geometric construction of unrestricted representations.
