The central city economical development has the vigor extremely, the economic society is in the fast reforming process, this needs the central city correspondingly to carry on the administrative system, the financial system innovation, by meets the central city rapid needs.
By the positive analysis of economic construction, administrative system and financial relationship of the central city——Dalian, this paper pointed out the systematic restricting factors of the development of Chinese central cities and drew the conclusion of proper tendency between the administrative system of central cities and the financial relationship of center towns and suburb districts or counties.
By taking the central city---Dalian as an example, the positive analysis of administrative system and financial relationship of center towns and suburb districts or counties was carried out, and the developing course since the Reform and Opening up was introduced, so that the reforming direction of administrative and financial system would be found out according to the requirements of Big-Dalian development.
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.
