Қарағанды университетінің хабаршысы. Математика сериясыIn the paper, the Gagliardo–Nirenberg type inequalities for smoothness spaces Bpqsτ(Tn) of Nikol’skii–Besov type and spaces Fpqsτ(Tn) of Lizorkin–Triebel type both related to Morrey spaces over n-dimensional torus for some range of the parameters s, p ...

Dimensionality Reduction and Uncertainty Quantification for Inverse Problems [PDF]
, 2015 Many inverse problems in science and engineering involve multi-experiment data and thus require a large number of forward simulations. Dimensionality reduction techniques aim at reducing the number of forward solves by (randomly) subsampling the data. In

A detectability criterion and data assimilation for nonlinear differential equations [PDF]
, 2018 In this paper we propose a new sequential data assimilation method for nonlinear ordinary differential equations with compact state space. The method is designed so that the Lyapunov exponents of the corresponding estimation error dynamics are negative ...

Aspects of random geometric graphs: Pursuit-evasion and treewidth [PDF]
, 2015 In this thesis, we studied two aspects of random geometric graphs: pursuit-evasion and treewidth. We first studied one pursuit-evasion game: Cops and Robbers. This game, which dates back to 1970s, are studied extensively in recent years.

The probability of connectivity in a hyperbolic model of complex networks [PDF]
, 2016 We consider a model for complex networks that was introduced by Krioukov et al. (Phys Rev E 82 (2010) 036106). In this model, N points are chosen randomly inside a disk on the hyperbolic plane according to a distorted version of the uniform distribution ...

Results in PhysicsThe evolution of a polydisperse ensemble of prolate and oblate ellipsoidal crystals in a supercooled one-component melt is theoretically studied. The volume growth rates for prolate and oblate ellipsoids are analytically found and compared at the same ...

On the structure of λ-Cantor set with overlaps [PDF]
, 2019 Given λ∈(0,1), let Eλ be the self-similar set generated by the iterated function system (IFS) {x/3,(x+λ)/3,(x+2)/3}. Then Eλ is a self-similar set with overlaps.

A homotopy perturbation method for fractional-order advection-diffusion-reaction boundary-value problems [PDF]
, 2017 In this paper we describe the application of the homotopy perturbation method (HPM) to two-point boundary-value problems with fractional-order derivatives of Caputo-type.

Induced random β-transformation [PDF]
, 2017 In this article we study the first return map defined on the switch region induced by the greedy and lazy maps. In particular we study the allowable sequences of return times, and when the first return map is a generalised L¨uroth series transformation ...
