Optimal Quadrature-Sparsification for Integral Operator Approximation [PDF]
SIAM Journal on Scientific Computing, 2018 The design of sparse quadratures for the approximation of integral operators related to symmetric positive-semidefinite kernels is addressed. Particular emphasis is placed on the approximation of the main eigenpairs of an initial operator and on the assessment of the approximation accuracy.
