On maximally inflected hyperbolic curves [PDF]
, 2014 In this note we study the distribution of real inflection points among the ovals of a real non-singular hyperbolic curve of even degree. Using Hilbert's method we show that for any integers $d$ and $r$ such that $4\leq r \leq 2d^2-2d$, there is a non ...

Numerical Investigation on Convergence Rate of Singular Boundary Method [PDF]
Mathematical Problems in Engineering, 2016 The singular boundary method (SBM) is a recent boundary-type collocation scheme with the merits of being free of mesh and integration, mathematically simple, and easy-to-program. Its essential technique is to introduce the concept of the source intensity factors to eliminate the singularities of fundamental solutions upon the coincidence of source and ...

Highly accurate special quadrature methods for Stokesian particle suspensions in confined geometries
, 2020 Boundary integral methods are highly suited for problems with complicated geometries, but require special quadrature methods to accurately compute the singular and nearly singular layer potentials that appear in them.
