Cubature formulas and Sobolev inequalities
, 2020 We study a problem in the theory of cubature formulas on the sphere: given $ \in (0, 1)$, determine the infimum of $\| \|_ = \sum_{i = 1}^n _i^ $ over cubature formulas $ $ of strength $t$, where $ _i$ are the weights of the formula $ $. This problem, which generalizes the classical problem of bounding the minimal cardinality of a cubature ...

Cubature formulas on combinatorial graphs
, 2011 The goal of the paper is to establish cubature formulas on combinatorial graphs. Two types of cubature formulas are developed. Cubature formulas of the first type are exact on spaces of variational splines on graphs. Since badlimited functions can be obtained as limits of variational splines we obtain cubature formulas which are "essentially" exact on ...

Cubature formulae for spheres, simplices and balls
Journal of Computational and Applied Mathematics, 2004 The paper is organized in 5 Sections. The first two contain respectively the motivation for the choice of the subject and some results concerning properties of polyharmonic functions. In Section 3, cubature on the sphere \(S(r)=\{x\in\mathbb{R}^n:| x| =r\}\) on the form \[ \int_{S(r)}\mu(\xi) \,d\sigma(\xi)\simeq \sum^{m-1}_{j=0} A_j(r)\int_{S(r_j)}\mu(

Existence of Gaussian cubature formulas
, 2011 We provide a necessary and sufficient condition for existence of Gaussian cubature formulas. It consists of checking whether some overdetermined linear system has a solution and so complements Mysovskikh's theorem which requires computing common zeros of orthonormal polynomials. Moreover, the size of the linear system shows that existence of a cubature
