The theory of generalized Fourier Series can be applied to the approximation of linear operator relationships. To demonstrate the computational results in using this approach several example problems where analytic solutions or quasi-analytic solutions exist are used for the testing the generalized Fourier...

Linear Approximation:The linear approximation, or linearization, of a functionf(x)atx=ais an approximation of the function using a straight line. This approximation is only accurate for values nearx=a. The linear approximation of a functionf(x)isf(x)≈f(a)+f′(a)...
A new numerical method called linearized and rational approximation method is presented to solve non-linear evolution equations. The utility of the method is demonstrated for the case of differentiation of functions involving steep gradients. The solution of Burgers' equation is presented to illustrate ...
For the Cauchy problem a constructive approximation method is introduced. This procedure yields a sequence (fn) of approximate densities, uniformly converging to the problem's global classical solution with linear convergence velocity.DOI: 10.1002/mma.1670060103 被引量: 1 ...
We prove the existence and uniqueness of a global solution of a damped quasilinear hyperbolic equation. Key point of our proof is the use of the Yosida approximation. Furthermore, we apply a method based on a specific integral inequality... M Aassila - 《J.egyptian Math.soc》 被引量: 0...
In linear approximation this leads to the usual phenomenological equations, obeying reciprocal relations in the form given by Casimir. The fluctuations about this average behaviour are also fully described by the master equation; as an example the Nyquist formula is derived....
The errors made on the computation of the sound field are first caused by the use of the parabolic approximation. In [14], F. Tappert gives for a simple case a comparison between an exact solution and the solution of the parabolic equation. The errors are also caused by the technique use...
This paper concerns the linear multistep approximation of an abstract dissipative linear sectorial evolution equation on a Banach space X. We study how well the semigroup generated by a sectorial operator A is approximated by the numerical semigroup generated by a q‐step, strictly A (α)‐stabl...
