Аннотация:One-phase models of inverse Stefan problems with unknown temperature-dependent convection coefficients are considered. Final observation is specified as additional information on the solution of the direct Stefan problem. For such inverse problems we justify the corresponding mathematical statements: to determine coefficients multiplying the lowest order derivatives in quasilinear parabolic equations in a one-phase domain with an unknown moving boundary. On the basis of the duality principle conditions for the uniqueness of their smooth solution are obtained. The sets of admissible solutions preserving the uniqueness property are indicated.
