Mixed Jacobi-Fourier spectral method for Fisher equation
Mathematical Modelling and Analysis, 2018 In this paper, we propose a mixed Jacobi-Fourier spectral method for solving the Fisher equation in a disc. Some mixed Jacobi-Fourier approximation results are established, which play important roles in numerical simulation of various problems defined in ...

Eliminating Nonuniform Smearing and Suppressing the Gibbs Effect on Reconstructed Images
Computers, 2020 In this work, the problem of eliminating a nonuniform rectilinear smearing of an image is considered, using a mathematical- and computer-based approach. An example of such a problem is a picture of several cars, moving with different speeds, taken with a

Charmonium spectral functions with the variational method in zero and finite temperature lattice QCD [PDF]
, 2011 We propose a method to evaluate spectral functions on the lattice based on a variational method. On a lattice with a finite spatial extent, spectral functions consist of discrete spectra only. Adopting a variational method, we calculate the locations and
