We consider the problem of the optimal recovery of solutions of the heat equation on the torus $\mathbb T$ from a finite set of inaccurate Fourier coefficients of the initial temperature. In addition, accuracy conditions on subspaces of trigonometric polynomials of fixed degree are imposed on these methods.
Keywords: optimal recovery, heat equation, trigonometric polynomials.
Mots-clés : Fourier transform
