Reaction-Diffusion Equations and Systems, i.e. . = .(.), we may alternatively view (5.1.1) as a generalization of the ODE . For such equations, we have, for the case of a Lipschitz continuous ., a local existence theorem, the Picard-Lindelöf theorem. This says that for given initial value ., we may find some . > 0 with the property that a unique solution exists for 0 ≤ . < ..

The Moser Iteration Method and the Regularity Theorem of de Giorgi and Nash,e homogeneous equation. Thus, we shall investigate (weak) solutions of . where the coefficients . are (measurable and) bounded and satisfy an ellipticity condition. We thus assume that there exist constants 0 < λ ≤ . < ∞ with . for all . in the domain of definition . of . and all . ∈ ℝ., and ..

Transport development is of great significance to national construction. In the 1960s, Chinese transportation was dominated by land transportation, and bridge construction was the basis for land transportation. Masonry arch bridges include stone arch bridges, plain concrete arch bridges and more.
