Fourier smoothed pre-corrected trapezoidal rule for solution of Lippmann-Schwinger integral equation

Ambuj Pandey, Akash Anand

For the numerical solution of the Lippmann-Schwinger equation, while the pre-corrected trapezoidal rule converges with high-order for smooth compactly supported densities, it exhib…

The Cauchy dual subnormality problem for cyclic -isometries

Akash Anand, Sameer Chavan, Zenon Jan Jabłoński +1

The Cauchy dual subnormality problem asks whether the Cauchy dual operator of a -isometry is subnormal. Recently this problem has been solved in the negative. Here we show that…

Trefftz Finite Elements on Curvilinear Polygons

Akash Anand, Jeffrey S. Ovall, Samuel Reynolds +1

We present a Trefftz-type finite element method on meshes consisting of curvilinear polygons. Local basis functions are computed using integral equation techniques that allow for t…
