We consider the Cauchy problem (x)n=atr + bx + f(t, x, x), x(0)=0. We prove the existence of continuously differentiable solutions and study their asymptotic behavior for t + 0.Translated from Ukrainskii Matematicheskii Zhurnal, Vol. 43, No. 2, pp. 187–193, February, 1991. 相似文献

An asymptotic expansion of the solution to the Neumann problem for a second-order equation in a thin domain with peak-like
edge is constructed and justified. Owing to the sharpness of the edge, the procedure of dimension reduction leads to a degenerate
limit equation on the longitudinal cross-section of the domain and a solution has irregular behavior near the boundary. Bibliography:

The spectrum of the elasticity problem for a spiked body 总被引:2,自引:1,他引:1
S. A. Nazarov 《Siberian Mathematical Journal》2008,49(5):874-893
We establish the existence of continuous spectrum for the operator of the linear elasticity problem in a three-dimensional domain with a sufficiently sharp spiked singularity of the boundary. We obtain some information about the structure of the spectrum and verify the weighted Korn inequality, which enables us to prove that the spectrum is discrete for insufficiently sharp spikes. We state some open questions. 相似文献
