Simply Exponential Approximation of the Permanent of Positive Semidefinite Matrices

, 2018
I will present a deterministic polynomial time c^n approximation algorithm for the permanent of positive semidefinite matrices where c ~ 4.84. This is through a natural convex programming relaxation and proving a PSD variation of the Van der Waerden's ...

On the Convergence of a Family of Chlodowsky Type Bernstein-Stancu-Schurer Operators

Journal of Function Spaces, 2018
We construct a new family of univariate Chlodowsky type Bernstein-Stancu-Schurer operators and bivariate tensor product form. We obtain the estimates of moments and central moments of these operators, obtain weighted approximation theorem, establish ...

The Shapley-Folkman Theorem and the Range of a Bounded Measure: An Elementary and Unified Treatment [PDF]

We present proofs, based on the Shapley-Folkman theorem, of the convexity of the range of a strongly continuous, finitely additive measure, as well as that of an atomless, countably additive measure.

The approximation theorem for the Λμ-calculus

Mathematical Structures in Computer Science, 2015
We consider a notion of approximation for terms of de Groote–Saurin Λμ-calculus. Then, we introduce an intersection type assignment system for that calculus which is invariant under subject conversion. The type assignment system also induces a filter model, which is an extensional Λμ-model in the sense of Nakazawa and Katsumata.

Diophantine approximation and the subspace theorem [PDF]

Diophantine approximation explores how well irrational numbers can be approximated by rationals, with foundational results by Dirichlet, Hurwitz, and Liouville culminating in Roth's theorem.

On a New Modification of Baskakov Operators with Higher Order of Approximation

Mathematics
A new Goodman–Sharma-type modification of the Baskakov operator is presented for approximation of bounded and continuous functions on [0,∞). We study the approximation error of the proposed operator.

Weierstrass approximation theorem

U ovom radu proučavamo Weierstrassov aproksimacijski teorem, koji tvrdi da se svaka neprekidna realna funkcija na zatvorenom intervalu može uniformno aproksimirati polinomima.

Hardy-Littlewood-Sobolev Theorem for Bourgain-Morrey Spaces and Approximation

European Journal of Mathematical Analysis
In this paper, we establish an extension of the Hardy-Littlewood-Sobolev theorem to the setting of the Bourgain-Morrey space Mαq,p(Rd) (1 ≤ q, p, α ≤ ∞), which theory goes back to Bourgain in 1991.

An Approximation Theorem on Some Convex Domains [PDF]

, 1991
Let Ωbe a convex domain with real analytic boundary which is a generalized type of the complex ellipsoid. Then the approximation theorem in the HP-sense holds in Ω.長崎大学教育学部自然科学研究報告.
