The paper mainly introduces the study results in national scientific and technical key task of 17—02—02 special topic concerning rational geometry and optimizing design of high arch dam ,stress and stability analysis methods,aseismic design of arch dam ,material characteristic of mass concrete, reliability analysis of arch dam, design criteria of high concrete arch clam, rational arrangement and structure design of pressure steel conduit with high water head and big diameter and so on.
Motivated by the physical concept of special geometry, two mathematical constructions are studied which relate real hypersurfaces to tube domains and complex Lagrangian cones, respectively.
The theory is applied to the case of cubic hypersurfaces, which is the one most relevant to special geometry, obtaining the solution of the two classification problems and the description of the corresponding homogeneous special K?hler manifolds.
The first part of this paper describes the construction of pseudo-Riemannian homogeneous spaces with special curvature properties such as Einstein spaces, using corresponding known compact Riemannian ones.
In the special case whenFn is the projective spaceRPn, one also obtains the upper bound.
Except for the Borel and some special cases a corresponding result is not known for the semi-centre of the enveloping algebra ofp.
A special topic has also been emphasised in 2001 with a topical issue on Interdisciplinary Physics based on invited papers at the conference APFA-2 (Applications of Physics to Financial Analysis) in Liège, Belgium.
The special topic was added in response to numerous requests for information on new and innovative methods that could be applied in the growing renewable fuels industry.
Special Topic Interball-1: first scientific results
Special Topic: Interball-2: first scientific results
For each of these major approaches, several subcategories and special topic areas are noted and discussed.
