Inhomogeneous parabolic equations on unbounded metric measure spaces [PDF]

open access: yes, 2012
We study the inhomogeneous semilinear parabolic equation ut = Δu + up + f(x), with source term f independent of time and subject to f(x) ≥ 0 and with u(0, x) = φ(x) ≥ 0, for the very general setting of a metric measure space. By establishing Harnack-type

Multisector Parabolic Equation Method for Scattering From Impenetrable Objects in Fluid Waveguides

open access: yesIEEE Access, 2021
Parabolic equation methods are a robust and efficient tool for modeling long-range acoustic propagation in range-dependent waveguides. A lesser known, but equally effective, application of parabolic equations is to the scattering problem.
