Resumen de Sinc approximation of the heat flux on the boundary of a two-dimensional finite slab

P.H. Quan, D.D. Trong, Alain Pham Ngoc Dinh

• 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.
