An inverse boundary value problem for the heat equation is considered on the interval (0, 1), where the heat conductivity γ(t, x) is piecewise constant and the point of discontinuity depends on time: γ(t, x) = k 2 for 0 < x < s(t) and γ(t, x) = 1 for s(t) < x < 1. It is shown that k and s(t) on the time interval [0, T ] are determined from the partial… (More)
