Two-dimensional arrays with maximal complexity

2 years ago

Abstract We present natural bounds for the complexity function of two-dimensional arrays, and we study the shape of the maximal…

On Lp norms and the spectral radius of operators in Hilbert spaces

2 years ago

Abstract We prove that \(lim_{p\rightarrow \infty}k\) \(\left \Vert f\right \Vert _{+p}^{+p}\diagup \left \Vert f\right \Vert _{p}^{p}=\left \Vert f\right \Vert _{\infty}\)…

Two-dimensional total palindrome complexity

2 years ago

Abstract We initiate a comparative study of the properties of total palindrome complexity for binary words and arrays. From this…

Programmed motion with homogeneity assumptions

2 years ago

Abstract We consider the problem : Given a planar region \(T_{orb}\) described by one inequality \(g(x,y)\leq c_{0}\), find the potentials…

Comment on “Modeling groundwater flow with random hydraulic conductivity using radial basis function partition of unity method” by Shile et al. (2024)

2 years ago

Abstract The goal of this article is to explain some striking discrepancies between the Monte Carlo inferences for flow in…

Controlling numerical diffusion in solving advection-dominated transport problems

2 years ago

Abstract Numerical schemes for advection-dominated transport problems are are evaluated in a comparative study. Explicit and implicit finite difference methods…

A Stancu type extension of the Cheney-Sharma Chlodovsky operators

2 years ago

Abstract In this paper we introduce a Stancu type extension of the Cheney-Sharma Chlodovsky operators based on the ideas presented…

Localization of energies in Navier–Stokes models with reaction terms

2 years ago

Abstract We analyze a general class of coupled systems of stationary Navier-Stokes type equations with variable coefficients and non-homogeneous terms…

Vector fixed point approach to control of Kolmogorov differential systems

2 years ago

Abstract The paper presents a vector approach to control problems for systems of equations. The method is described in the…

Optimal approximation of unique continuation

2 years ago

Abstract We consider numerical approximations of ill-posed elliptic problems with conditional stability. The notion of optimal error estimates is defined including…
