The differentiability of solutions for elliptic equations which degenerate on part of the boundary of a convex domain
《Applied Mathematics(A Journal of Chinese Universities)》2018年第4期421-435,共15页SONG Jia-xin CAO Yi 
Research supported by the National Natural Science Foundation of China(11671243);the Shaanxi natural science basic research project of China(2018JM1020)
In this paper,we study the differentiability of solutions on the boundary for equartions of type L;u=;u/x;+|x|;;u/y;=f（x,y）,where λ is an arbitrary positive number. By introducing a proper metric that is related to...

Numerical estimation of the piecewise constant Robin coefficient by identifying its discontinuous points
《Applied Mathematics(A Journal of Chinese Universities)》2015年第1期1-16,共16页CHENG Xiao-liang YU Yuan-jie 
Supported by the Key Project of the Major Research Plan of the NSFC(91130004)
We propose a new numerical method for estimating the piecewise constant Robin coefficient in two-dimensional elliptic equation from boundary measurements. The Robin in- verse problem is recast into a minimization of a...

DIMENSION AND DIFFERENTIABILIIY OF A CLASS OF FRACTAL INTERPOLATION FUNCTIONS被引量：2
《Applied Mathematics(A Journal of Chinese Universities)》1996年第1期85-100,共16页WANG GUOZHONG Department of Mathematics, Zhejiang University Hangzhou 310027 
Supported by the National Natural Science Foundation of China and the Natural Science Foundtion of Zhejiang Province.
In this paper, a new iterated function system consisting of non-linear affinemaps is constructed. We investigate the fractal interpolation functions generated bysuch a system and get its differentiability, its box dim...

ON THE DIFFERENTIABILITY OF THE PARITY PROGRESSIVE POPULATION SEMIGROUP
《Applied Mathematics(A Journal of Chinese Universities)》1994年第3期223-230,共8页施德明 杨录山 
We are concerned with t he differentiability of the parity progressive population semigroup under certain weak assumptlons. We prove by studying the properties of the spectrum of the parity progressive operator of pop...
