A sharp error estimate of piecewise polynomial collocation for nonlocal problems with weakly singular kernels

Minghua Chen, Wenya Qi, Jiankang Shi +1

As is well known, using piecewise linear polynomial collocation (PLC) and piecewise quadratic polynomial collocation (PQC), respectively, to approximate the weakly singular integra…
