Zeros of Approximate Functional Approximations [PDF]
Mathematics of Computation, 1967 The gN(s) are of interest as approximations to the Riemann zeta function. Let s = or + it. In [1], it was shown that for t sufficiently large, gi(s) and g2(s) have their zeros on the critical line ar = 2. After encountering analytical difficulties in attempting to extend this theorem to further N, the calculations described below were undertaken.

The Zeldovich approximation [PDF]
, 2014 This year marks the 100th anniversary of the birth of Yakov Zel'dovich. Amongst his many legacies is the Zel'dovich approximation for the growth of large-scale structure, which remains one of the most successful and insightful analytic models of ...

The Solution of the Inverse Problem of Identifying the Thermal Conductivity Tensor in Anisotropic Materials [PDF]
Journal of Mechanical Engineering, 2021 On the basis of A. N. Tikhonov's regularization theory, a technique has been developed for solving inverse heat conduction problems of identifying the thermal conductivity tensor in a two-dimensional domain.

Approximations of non-homogeneous Markov chains on abstract states spaces
Bulletin of Mathematical Sciences, 2021 Approximations of nonhomogeneous discrete Markov chains (NDMC) play an essential role in both probability and statistics. In all these settings, it is crucial to consider random variables in appropriate spaces.

Approximation Schemes for Partitioning: Convex Decomposition and Surface Approximation
, 2014 We revisit two NP-hard geometric partitioning problems - convex decomposition and surface approximation. Building on recent developments in geometric separators, we present quasi-polynomial time algorithms for these problems with improved approximation ...

A Test of the Adhesion Approximation for Gravitational Clustering [PDF]
, 1993 We quantitatively compare a particle implementation of the adhesion approximation to fully non--linear, numerical nbody simulations. Our primary tool, cross--correlation of nbody simulations with the adhesion approximation, indicates good agreement ...

Reduction of decision rule of multivariate interpolation and approximation method in the problem of data classification [PDF]
Компьютерные исследования и моделирование, 2016 This article explores a method of machine learning based on the theory of random functions. One of the main problems of this method is that decision rule of a model becomes more complicated as the number of training dataset examples increases.
