Chinese Annals of Mathematics,Series B 1990年第1期11卷 1-14页

作者：陆启铿 Dedicated to the Tenth Anniversary of CAM Institute of Mathematics Academia SinicaBeijingChina

By introducing the horosphere coordinate of a unit ball Bn in Cn and an integraltransformation formula of functions in such coordidates,the author constructs the heatkernel HBn（z,w,t）of the heat equation associated to the Bergman metric of Bn.That iswhere cn is a well-defined constant and r（z,w）is the geodesic destance of two points zand w of Bn and t∈ R+.Sincethenis the Green function of the topological product space Bm×Bn.

Suturing and stapling are the most comm on fixation procedures employed for wound closure after critical injuries or surgery[1,2].Such procedures require penetration in the tissues,thus may cause infections,induce strain and raise potential aesthetic issues[3,4].Sutureless approaches seem to be much more appropriate fixation methods through producing an adhesive con tact at the surface between tissues and adhesives under physiological conditions[5-7],The existing adhesives,such as liquids or hydrogels,mostly depend on introducing binding interactions between hydrogel molecules and the polymer networks of tissues through the interfacial water[8,9].
