Positive Solutions of Emden Equations in Cone-Like Domains,∶ ./|.| ∈ Ω. Consider the nonlinear Dirichlet problem where δ ∈ ℝ and . >1. We shall be interested in . classical solutions. They might be discontinuous at the origin, and in this case they will be called . solutions and will be denoted by us, in contrast to the . solutions . ∈ ..(C) ∩ ..(C ∪ ∂.), .我正派 发表于 2025-3-27 09:55:29
A Parabolic Equation with a Mean-Curvature Type Operator,eracy for large gradients. The same type of operators arises also in thermodynamical context in the theory of convex free energy functionals, which are asymptotically linear as the gradient tends to infinity ; in particular this leads to the parabolic equation .. = . .

Identifying a Time Dependent Unknown Coefficient in a Nonlinear Heat Equation,al equation. The trace type functional problem can be solved in a relatively straightforward manner and the solution shown to lead to a solution for the inverse problem. This approach allows us to investigate the inverse problem with various alternative overspecified conditions.减去 发表于 2025-3-28 01:52:08

Logico-Mathematical Preliminaries,s. Namely, we account for driver hours of service regulations, time-dependent travel times, time-dependent fuel consumption and refueling deviations. The latter stems from the fact that we consider non homogeneous fuel prices at refueling stations. Considering a given origin and destination along wi
