Magneto-micropolar fluid motion: global existence of strong solutions

Abstract and Applied Analysis, 1999
By using the spectral Galerkin method, we prove a result on global existence in time of strong solutions for the motion of magneto-micropolar fluid without assuming that the external forces decay with time. We also derive uniform in time estimates of the

Projective parameterized linear codes

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
In this paper we estimate the main parameters of some evaluation codes which are known as projective parameterized codes. We find the length of these codes and we give a formula for the dimension in terms of the Hilbert function associated to two ideals,

Strong Limiting Bounds for Maximal Uniform Spacings

The Annals of Probability, 1982
Let $U_1, U_2 \cdots$ be a sequence of independent uniformly distributed random variables on (0, 1) and $M_n$ be the largest spacing induced by $U_1, \cdots, U_n$. We show that $P(M_n \geq (\log n + 2 \log_2n + \log_3n + \cdots + \log_jn)/n \text{i.o.}) = 1$, where $\log_j$ is the $j$ times iterated logarithm, and $j \geq 4$. If $1 = N_1 < N_2 < \cdots

Uniform Bounds of Aliasing and Truncated Errors in Sampling Series of Functions from Anisotropic Besov Class

Abstract and Applied Analysis, 2013
Errors appear when the Shannon sampling series is applied to approximate a signal in real life. This is because a signal may not be bandlimited, the sampling series may have to be truncated, and the sampled values may not be exact and may have to be ...

An alternate measure of the cumulative residual Sharma-Taneja-Mittal entropy

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
We define a new alternate measure of the cumulative residual Sharma-Taneja-Mittal entropy. For this measure, there are given upper and lower bounds, is introduced a consistent test based on the uniform distribution and some concrete numerical examples ...

Some remarks on gradient estimates for heat kernels

Abstract and Applied Analysis, 2006
This paper is concerned with pointwise estimates for the gradient of the heat kernel Kt, t>0, of the Laplace operator on a Riemannian manifold M. Under standard assumptions on M, we show that ∇Kt satisfies Gaussian bounds if and only if it satisfies ...

Exponential Bounds for the Density of the Law of the Solution of an SDE with Locally Lipschitz Coefficients

Mathematics
Under the uniform Hörmander hypothesis, we study the smoothness and exponential bounds of the density of the law of the solution of a stochastic differential equation (SDE) with locally Lipschitz drift that satisfies a monotonicity condition.

Sharp indistinguishability bounds from non-uniform approximations

, 2021
We study the problem of distinguishing between two symmetric probability distributions over $n$ bits by observing $k$ bits of a sample, subject to the constraint that all $k-1$-wise marginal distributions of the two distributions are identical to each other. Previous works of Bogdanov et al.
