A least squares radial basis function finite difference method with improved stability properties
Igor Tominec, Elisabeth Larsson, Alfa Heryudono
Localized collocation methods based on radial basis functions (RBFs) for elliptic problems appear to be non-robust in the presence of Neumann boundary conditions. In this paper we…

Space-Time Collocation Method: Loop Quantum Hamiltonian Constraints
Alec Yonika, Alfa Heryudono, Gaurav Khanna
A space-time collocation method (STCM) using asymptotically-constant basis functions is proposed and applied to the quantum Hamiltonian constraint for a loop-quantized treatment of…
