When H(y,x)is assumed to be nondecreasing inγ∈R and convex and radial and positively homogeneous of degree 1 in x∈R~m,the uniqueness of bounded viscosity solutions is established with bounded continuous initial data u(p,0)=g(p),the solution is given by the Hopf-Lax formula u(p,t)=min_(q∈G){h(t/q~(-1)·P)V g(q)} where h is the quasiconvex dual of H(y,x)i.
当函数H(y,x)对变量y∈R是单调增的,而关于变量x∈R~m是凸的、径向且一阶齐次时,建立了该方程在有界连续初值u(p,0)=g(p)下有界粘性解的存在唯一性,其解由Hopf-Lax公式给出u(p,t)=min_(q∈G){h(t/q~(-1)·p)V g(q)},其中函敦h是由函数H(y,z)关于变量x∈R~m的拟凸对偶提升到G上的,且关于Carnot-Carathéodory距离是径向的。
