On operators induced by weakly 2-singular kernels [PDF]

open access: yesCzechoslovak Mathematical Journal, 1995
It is shown that a kernel \(K(x,y)= L(x,y)/| x-y|^{1/2}\) for \(x\neq y\) in \([0,1]\) defines a \((q,2)\)-summing operator on \(L_\infty(0,1)\) for any \(q>2\) provided that \(\sup_x| L(x,\cdot)|\in L_{2,1}(0,1)\).

An efficient spectral method for nonlinear Volterra integro-differential equations with weakly singular kernels

open access: yesMathematical Modelling and Analysis
For Volterra integro-differential equations (VIDEs) with weakly singular kernels, their solutions are singular at the initial time. This property brings a great challenge to traditional numerical methods. Here, we investigate the numerical approximation
