The regularity of weak solutions for the quasi-linear diffraction problems with linear growth coefficients
Tan Qi-jian · 2008
N-dimeansional quasi-linear diffraction problems with special principle part and linear growth coefficients are considered. By using estimates and average functions methods, the authors prove some regularity properties of the weak solutions in the neighborhood of the inner boundary, and extend these regularity results from linear problem to the special quasi-linear one.
