Matrix-free iterative processes with least-squares error damping for nonlinear systems of equations

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2018
New iterative processes for numerical solution of big nonlinear systems of equations are considered. The processes do not require factorization and storing of Jacobi matrix and employ a special technique of convergence acceleration which is called least ...

Suspense [PDF]

open access: yes
In a dynamic model of sports competition, we show that when spectators care only about the level of effort exerted by contestants, rewarding schemes that depend linearly on the final score difference provide more efficient incentives for efforts than ...

High order compact finite difference schemes for a nonlinear Black-Scholes equation [PDF]

open access: yes
A nonlinear Black-Scholes equation which models transaction costs arising in the hedging of portfolios is discretized semi-implicitly using high order compact finite difference schemes. In particular, the compact schemes of Rigal are generalized.

Nonstandard finite difference schemes for differential equations

open access: yesSahand Communications in Mathematical Analysis, 2014
In this paper, the reorganization of the denominator of the discrete derivative and nonlocal approximation of nonlinear terms are used in the design of nonstandard finite difference schemes (NSFDs).

On dispersive difference schemes

open access: yesPhysica D: Nonlinear Phenomena, 1986
In 1944, J. von Neumann proposed a difference scheme for calculating one- dimensional compressible flows with shocks. He conjectured that the approximations converge in the weak sense to the appropriate discontinuous solution of the differential equations.

A simple parallel prefix algorithm for compact finite-difference schemes [PDF]

open access: yes
A compact scheme is a discretization scheme that is advantageous in obtaining highly accurate solutions. However, the resulting systems from compact schemes are tridiagonal systems that are difficult to solve efficiently on parallel computers ...
