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-Lindel?f 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 . ∈ ?., and ..
