The embedding theorems for anisotropic Nikol’skii-Besov spaces with generalized mixed smoothness [PDF]
Қарағанды университетінің хабаршысы. Математика сериясы, 2021 The theory of embedding of spaces of differentiable functions studies the important relations of differential (smoothness) properties of functions in various metrics and has a wide application in the theory of boundary value problems of ...

Trigonometric interpolation [PDF]
Proceedings of the Edinburgh Mathematical Society, 1992 We consider interpolation at 2n equidistant nodes in [0,π) from the space ℱN spanned by sines and cosines of odd multiples of x. This interpolation problem is shown to be correct for an arbitrary sequence of derivatives specified at all the nodes.

On Trigonometric Interpolation [PDF]
Proceedings of the American Mathematical Society, 1952 which in case of derivatives take the place of (1). (ArP(t)/(At)r is the rth divided difference formed with the constant increment At =2wx/(2n+1)), and we shall show that here, as in Marcinkiewicz's case, the exponent 2 can be replaced by any p ?1. As an application, we shall give bounds for the p-norms of the derivatives of interpolating polynomials ...

Subperiodic trigonometric subsampling: A numerical approach [PDF]
, 2017 We show that Gauss-Legendre quadrature applied to trigonometric poly- nomials on subintervals of the period can be competitive with subperiodic trigonometric Gaussian quadrature. For example with intervals correspond- ing to few angular degrees, relevant

An exponential-trigonometric spline minimizing a seminorm in a Hilbert space
Advances in Difference Equations, 2020 In the present paper, using the discrete analogue of the operator d 6 / d x 6 − 1 $\mathrm{d} ^{6}/\mathrm{d} x^{6}-1$ , we construct an interpolation spline that minimizes the quantity ∫ 0 1 ( φ ‴ ( x ) + φ ( x ) ) 2 d x $\int _{0}^{1}(\varphi {'''}(x)+\

Reconstruction of a polynomial from its Radon projections [PDF]
, 2005 A polynomial of degree $n$ in two variables is shown to be uniquely determined by its Radon projections taken over $[n/2]+1$ parallel lines in each of the $(2[(n+1)/2]+1)$ equidistant directions along the unit circle.Comment: SIAM J. Math. Anal.
