• Relative Chebyshev Centers in Hilbert Space

  سند علمی۲۰۰۷Robert Huotari

  We characterize inner product spaces in terms of the relationship between the relative Chebyshev center of a set and the absolute Cheby-shev center of an associated set. A consequence of the characterization is that an existing nite algorithm can be adapted to calculate the cente

• Some properties of the $\alpha$-Chebyshev wavelets approximation with H$\ddot{O}$lder function

  مقاله۲۰۲۵Mathematical Analysis and Convex OptimizationH. Mazaheri, A. W. Safi, M Kalantary

  In this paper, we consider $\alpha-$Chebyshev polynomials, $\alpha-$Chebyshev wavelet approximation and h$\ddot{o}$lder of order $l$. We estimate $\alpha-$Chebyshev-wavelet approximation of a function $f$ having satisfy condition h$\ddot{o}$lder where $f$ is expanded in terms of

  سند علمی۲۰۱۴BMC Medical ImagingDominik Vollherbst, Stefan Fritz, Sascha Zelzer, Miguel F. Wachter

  BACKGROUND Size and shape of the treatment zone after Irreversible electroporation (IRE) can be difficult to depict due to the use of multiple applicators with complex spatial configuration. Exact geometrical definition of the treatment zone, however, is mandatory for acute treat

• Operator equalities and Characterizations of Orthogonality in Pre-Hilbert C *-Modules

  مقاله‌ی دسترسی آزاد۲۰۲۱Proceedings of the Edinburgh Mathematical Society['Rasoul Eskandari', 'Mohammad Sal Moslehian', 'Dan Popovici', '']

  In the first part of paper, we use states on $C^*$-algebras in order to establish some equivalent statements equality triangle inequality, as well parallelogram identity for elements a pre-Hilbert $C^*$-module. We also characterize case inequality adjointable operators Hilbert Th

• Valuing American Put Options Using Chebyshev Polynomial Approximation

  سند علمی۲۰۰۵Guglielmo Maria Caporale, Mario Cerrato

  This pa per suggests a simple valuation method based on Chebyshev approximation at Chebyshev nodes to value American put options. It is similar to the approach taken in Sullivan (2000), where the option`s continuation region function is estimated by using a Chebyshev polynomial.
