Approximating sub-Riemannian structures by Riemannian metrics and spectral convergence
We construct an approximating sequence of Riemannian metrics tailored to a given sub-Riemannian structure. We prove that the sequence of associated Riemannian volumes converge to Popp's volume and we then proceed to study the spectral convergence of the ...

Error Estimates on Approximating the Finite Fourier Transform of Complex-Valued Functions via a Pre-Grüss Inequality [PDF]
, 2004 Some estimates for the error in approximating the Finite Fourier Transform in terms of exponential means via a pre-Grüss inequality for complex-valued functions are ...

Approximating Minimum Reset Sequences [PDF]
, 2011 We consider the problem of finding minimum reset sequences in synchronizing automata. The well-known Cerný conjecture states that every n-state synchronizing automaton has a reset sequence with length at most (n - 1)2. While this conjecture gives an upper bound on the length of every reset sequence, it does not directly address the problem of finding ...

Strong Convergence Theorems for Infinitely Nonexpansive Mappings in Hilbert Space
Fixed Point Theory and Applications, 2009 We introduce a modified Ishikawa iterative process for approximating a fixed point of two infinitely nonexpansive self-mappings by using the hybrid method in a Hilbert space and prove that the modified Ishikawa iterative sequence converges strongly to a ...

Real number approximation by a rational number in the approximating k-ary algorithm
Учёные записки Казанского университета: Серия Физико-математические науки, 2019 The best approximation by the irreducible fraction with the denominator not exceeding some specified value n was investigated. The aim of this study was to find the fastest approximation algorithm that enables to accelerate the convergence of the k-ary ...

Bootstrapping quantum process tomography via a perturbative ansatz
Nature Communications, 2020 Quantum process tomography represents one of the workhorses of quantum information processing, but suffers from exponential resource scaling. Here, the authors propose to efficiently infer general processes by approximating them through a sequence of two-

Strong well-posedness for a class of split variational inequalities with set-valued maps
پژوهشهای ریاضی, 2021 In this paper, we present a generalization of well-posedness for a system of split multi-valued variational inequalities with set-valued maps and establish a metric characterization for them. Moreover, we show that the strong well-posedness is equivalent

Abstract and Applied Analysis, 2022 In this paper, we introduce a proximal point algorithm for approximating a common solution of finite family of convex minimization problems and fixed point problems for k-demicontractive mappings in complete CAT(0) spaces.

Symmetry in the sequence of approximation coefficients [PDF]
Proceedings of the American Mathematical Society, 2013 Let $\{a_n\}_1^\infty$ and $\{θ_n\}_0^\infty$ be the sequences of partial quotients and approximation coefficients for the continued fraction expansion of an irrational number. We will provide a function $f$ such that $a_{n+1} = f(θ_{n\pm1},θ_n)$. In tandem with a formula due to Dajani and Kraaikamp, we will write $θ_{n \pm 1}$ as a function of $(θ_{n \
