The problem of reconstructing solutions of the singular heat equation on the positive part of the real axis at a certain moment of time is solved by inaccurate measurements of this solution at other previous moments of time. Explicit expressions for the optimal reconstruction method and its errors are obtained.
Keywords: Bessel operator, extremal problem, heat equation
Mots-clés : optimal reconstruction, Fourier–Bessel transform
