报告摘要：We investigated the asymptotic for the singular function xrlogvx with r > -1/2 and integer v > 0. We derived the formula of coefficients of the Legendre projection for xrlogvx, then proved various asymptotic formulas of the error in the Legendre projection of the singular function xrlogvx in L^2-norm. Computational results for different asymptotic formula with various values of r and v are presented, which show the numerical behaves of the asymptotics of these formulas, which coincide with the theoretical predictions.
