Consider solving the Dirichlet problem of Helmholtz equation on unbounded region R2Г with Г a smooth open curve in the plane. We use simple-layer potential to
In this paper we present a dynamic optimal method for adjusting the centering pa-rameter in the wide-neighborhood primal-dual interior-point algorithms for line
In [4] we proved that all Gauss methods areNτ(0)-compatible for neutral delay differential equations (NDDEs) of the form:y’(t) = ay(t) + by(t - τ) + cy’(t -
In this paper, a kind of rational cubic interpolation functionwith linear denominator is constructed. The constrained interpolation with constraint on shape of
This paper provides a theoretical justification to a overlapping domain decomposition method applied to the solution of time-dependent convection-diffusion prob
