By joining two harmonic homogeneous polynomial maps, Smith proved that every element of homotopy group Πm(Sm) has a harmonic representative for m≤7.Now we have proved the following main resul...
Ⅰ. INTRODUCTION Let M be a complete noncompact Riemannian manifold, R^+ be non-negative semi-realaxis, H_M(x, y, t ) be the heat kernel on M, P_t (x, y)
Let G be a Lie group. It is well-known that an involutive automorphism σ of G can determine a homogeneous symmetric space. In this letter, we generalize σ to a finite abelian group consisting of automorphisms of G, ...
The mass-screening of gastric cancer has been carried out for years in Shanghai. A huge number of data and samples have been accumulated in this work. But there are still difficulties in the diagnosis of gastric cance...
The family Porcellidae belonging to the superfamily Pleurotomariacea(Gastropoda)is characterized by coiled pseudoisostrophic or euomphaloid but protoconeh invariably dextral orthostrophic,having deep slit and narrow s...
Observations of the EUV and the soft X-ray of the sun have revealed many loop-like structures, which are rooted near the region with strong magnetic field in the photosphere, with their upper part extending out into t...
Fe82Si5B13, (Fe0.8Ni0.15V0.05)78Si8B14 and (Fe0.06Co0.85Ni0.06Nb0.03)75Si10B15 are three kinds of representative amorphous soft magnetic materials with low coercive force. After subjecting them to a adaptive heat trea...
In [1] an ordered tree is represented by a sequence of non-negative integers, and an algorithm is given to generate lexicographically all ordered trees with n vertices Now on the basis of [1] we define the representat...
