Query: Determination of a jump by Fourier and Fourier-Chebyshev series   By observing the equivalence of assertions on determining the jump of a
function by its differentiated or integrated Fourier series, we generalize a
previous result of Kvernadze, Hagstrom and Shapiro to the whole class of
functions of harmonic bounded variation and without finiteness assumption on
the number of discontinuities. Two results on determination of jump
discontinuities by means of the tails of integrated Fourier-Chebyshev series
are derived.
