变指数退化完全nonlinear elliptic方程解的正则性

Regularity of solutions to degenerate fully nonlinear elliptic equations with variable exponent

Yuzhou Fang, Vicentiu D. Radulescu, Chao Zhang

摘要:

考虑具有变指数双相型退化的完全非线性方程$$ \big[|Du|^{p(x)}+a(x)|Du|^{q(x)}\big]F(D^2u)=f(x). $$在适当的假设下,利用几何切向方法,结合紧致性和尺度技巧,得到了该方程黏性解的局部$C^{1,α}$正则性.

英文摘要:

We consider the fully nonlinear equation with variable-exponent double phase type degeneracies $$ \big[|Du|^{p(x)}+a(x)|Du|^{q(x)}\big]F(D^2u)=f(x). $$ Under some appropriate assumptions, by making use of geometric tangential methods and combing a refined improvement-of-flatness approach with compactness and scaling techniques we obtain the sharp local $C^{1,α}$ regularity of viscosity solutions to such equations.
