  • Beschreibung: We demonstrate the existence, uniqueness, and continuous dependence upon the data for the solution (u, v, s) of the free boundary value problem: ut = αuxx, vt = βvxx, 0 < x < s(t), 0ʚ< t ≤ T, u(x, 0) = ϕ(x), v(x, 0) = ψ(x), 0 ≤ x ≤ s(0) = b. –αux(0, t) = f(t), -βvx(0, t) = g(t), 0 < t ≤ T, αux(s(t), t) = –(γ + u(s(t),t))ṡ(t), βvx (s(t),t) = (μ – v(s(t),t)ṡ(t), 0 < t ≤ T, ṡ(t) = v(v(s(t),t))exp(–δ/v(s(t),t))F(u(s(t),t)), 0 < t ≤ T, where α, β, γ, δ, and μ are positive constants related to the physical constants.
