TY - EJOU AU - Li, Jin AU - Yu, Dehao TI - The Superconvergence of Certain Two-Dimensional Cauchy Principal Value Integrals T2 - The International Conference on Computational \& Experimental Engineering and Sciences PY - 2011 VL - 17 IS - 1 SN - 1933-2815 AB - The composite rectangle (midpoint) rule for the computation of multi-dimensional singular integrals is discussed, and the superconvergence results is obtained. When the local coordinate is coincided with certain priori known coordinates, we get the convergence rate one order higher than the global one. At last, numerical examples are presented to illustrate our theoretical analysis which agree with it very well. KW - DO - 10.3970/icces.2011.017.005
