Here we give a Voronovskaja formula of high order for linear combinations of the convolution operators(Gw,rf)(s)=∫0+∞∑j=1rαjKjw(t)f(st)dtt,where Kw is the Mellin–Gauss–Weierstrass kernel. This kind of operator provides a better order of pointwise approximation and leads to ...

1.3 for a discussion of previous results. While we were preparing this paper we became aware of the independent work [22], where this idea also appears. In particular, it is shown that always grows at least linearly in T and that is necessary for linear variance. Both of these results ...

In control system engineering, the Laplace transform is crucial for analyzing time functions. The inverse Laplace transform is equally important for deriving time-domain functions from their frequency-domain forms, with several properties beneficial for linear systems analysis. ...
In the derivation new mathematical techniques are presented. For both the straight line and the hexagon a discrete version of the "extended" formula is developed. 关键词: Convolution Image reconstruction Tomography DOI: 10.1109/TMI.1985.4307720 被引量: 155 年份: 1985 ...
[41] constructed an FVE scheme for the time fractional subdiffusion equation with the Riemann–Liouville fractional derivative, and applied a piecewise linear discontinuous Galerkin method in time, where the convergence rate in time wask1+α(0<α<1). In order to improve the results in [41], ...
