A pseudospectral method for the one-dimensional fractional Laplacian on R
(2021-01-15)
In this paper, we propose a novel pseudospectral method to approximate accurately and efficiently the fractional Laplacian without using truncation. More precisely, given a bounded regular function defined over R, we map ...
Numerical approximation of the fractional Laplacian on R using orthogonal families
(2020-12-01)
In this paper, using well-known complex variable techniques, we compute explicitly, in terms of the F12 Gaussian hypergeometric function, the one-dimensional fractional Laplacian of the complex Higgins functions, the complex ...
On the Evolution of the Vortex Filament Equation for regular M-polygons with nonzero torsion
(2019-09-03)
In this paper, we consider the evolution of the Vortex Filament equa- tion (VFE):
Xt = Xs ∧ Xss,
taking M-sided regular polygons with nonzero torsion as initial data. Us- ing algebraic techniques, backed by numerical ...
On the Relationship between the One-Corner Problem and the $M-$Corner Problem for the Vortex Filament Equation
(2018-06-28)
In this paper, we give evidence that the evolution of the vortex filament equation (VFE) for a regular M-corner polygon as initial datum can be explained at infinitesimal times as the superposition of M one-corner initial ...
The Vortex Filament Equation as a Pseudorandom Generator
(2015-08-01)
In this paper, we consider the evolution of the so-called vortex filament equation (VFE),
$$ X_t = X_s \wedge X_{ss},$$
taking a planar regular polygon of M sides as initial datum. We study VFE from a completely novel ...
Vortex filament equation for a regular polygon
(2014-12-31)
In this paper, we study the evolution of the vortex filament equation,$$ X_t = X_s \wedge X_{ss},$$with $X(s, 0)$ being a regular planar polygon. Using algebraic techniques, supported by full numerical simulations, we give ...
