There is presented an approach to find an approximation polynomial of a function with two variables based on the two dimensional discrete Fourier transform. The approximation polynomial is expressed through Chebyshev polynomials. There is given an uniform convergence result.

Discussion (0). Continue with ORCID to comment.

    A two-variable Chebyshev polynomial reconstruction of f(Q,T) gravity is shown to be algebraically identical to a truncated Taylor series, then fitted to Pantheon+SH0ES data.
