摘 要: | In1]we discussed the problems of calculus of variations withstrong nonlinearity.Its Euler equation is evidently the followingelliptic type equation of divergent form with strongly increasingcoefficients,(da(x,u,u_x))/(dx_) a(x,u,u_x)=0,x∈ΩR~n.(1)We get the interior regularities of the solutions of(1).It is justthe Hilbert's 19th problem in the ease with strong nonlinearity.
