• Resumen

  • We consider the two-dimensional problem of recovering globally in time the heat flux on the surface of a layer inside of a heat-conducting body from two interior temperature measurements. The problem is ill-posed. The approximation function is represented by a two-dimensional Sinc series and the error estimate is given.
