In this paper the complete double-series in the closed region expressing the double-variable functions and their partial derivatives are derived by the H-transforniution and Stockes transformation. Using the double-series, a series solution for the axisyinmetric boundary value problem of the elastic circular cylinder with finite length is presented.In a numerical example, the cylinder subjected to the axisymmetric traellens with various loaded regions is investigated and the distributions of the displacement sand stresses are obtained.It is possible to solve the axisymmetric boundary value problems in the eylinderical coordinates for other scientific fields by use of the method presented in this paper. 展开更多

New spaces of test functionals and distributions having kernels of the chaos decomposition in (Hn,n>0) are constructed. Their counterparts over Rm are completely characterized in terms of the H-transform. 展开更多

In this study, we investigate some properties of the conditioned superprocesses (subcritical or critical). Firstly, we give an equivalent description of the probability of the event that the total occupation time measure on a compact set is finite and some applications of this equivalent description. Our results are extensions of those of Krone (1995) from particular branching mechanisms to general branching mechanisms. We also prove a claim of Krone for the cases of d = 3, 4. Secondly, we study the local extinction property of the conditioned binary super-Brownian motion {X t , P μ ∞ }. When d = 1, as t goes to infinity, X t / $ \sqrt t $ converges to ηλ in weak sense under P μ ∞ , where η is a nonnegative random variable and λ is the Lebesgue measure on ?. When d ? 2, the conditioned binary super-Brownian motion is locally extinct under P μ ∞ . 展开更多
