Abstract One of the major telecommunication and network service providers in Indonesia is PT Indosat Tbk. During coronavirus (COVID-19) pandemic, daily stock price that company was influenced by government policies. This study addresses data movement from February 5, 2020 to 2021, resulted 243 data, using Geometric Brownian motion (GBM). The stochastic process realization this fluctuates increa...

let $n,t_1,...,t_k$ be distinct positive integers. a toeplitz graph $g=(v, e)$ denoted by $t_n$ is a graph, where $v ={1,...,n}$ and $e= {(i,j) : |i-j| in {t_1,...,t_k}}$.in this paper, we present some results on decomposition of toeplitz graphs.

This paper deals with some universal spaces. For every topological space $X$, the $T_1$ is viewed as bottom element of lattice $\mathcal{L}_X$. The class morphisms in $\mathrm{\mathbf{Top}}$ orthogonal to all spaces characterized. Also, we introduce new separation axioms and characterize them. Moreover, $X$ for which associated a spectral space. Finally, give characterizations such that their $...

A classical result of Sz.-Nagy asserts that a Hilbert space contraction operator T can be dilated to unitary $${{\mathcal {U}}}$$ , i.e., $$T^n = P_{{\mathcal {H}}}{{\mathcal {U}}}^n|{{\mathcal {H}}}$$ for all $$n =0,1,2,\ldots $$ . more general multivariable setting these ideas is the setup where (i) unit disk replaced by domain $$\Omega contained in $${{\mathbb {C}}}^d$$ (ii) an -contraction,...

We prove a quantitative version of Hilbert's irreducibility theorem for function fields: If $f(T_1,\ldots, T_n,X)$ is an irreducible polynomial over the field rational functions finite $\mathbb{F}_q$ characteristic $p$, then proportion $n$-tuples $(t_1,\ldots, t_n)$ monic polynomials degree $d$ which $f(t_1,\ldots, t_n,X)$ reducible out all $O(dq^{-d/2})$.

By $\mathcal{A}^2$ denote the class of analytic functions formBy form$f(z)=\sum_{n+m=0}^{+\infty}a_{nm}z_1^nz_2^m,$with {the} domain convergence $\mathbb{T}=\{z=(z_1,z_2)\in\mathbb C^2\colon|z_1|<1,\ |z_2|<+\infty\}=\mathbb{D}\times\mathbb{C}$ and$\frac{\partial}{\partial z_2}f(z_1,z_2)\not\equiv0$ in $\mathbb{T}.$ In this paper we prove some analogue Wiman's inequalityfor $f\in\mathcal{A...

Abstract Wiggle matching is an important and powerful technique in radiocarbon dating that can be used to improve the precision of calendar age estimates. All determinations require calibration provide This achieved by comparing against a curve $\mu ( \cdot )$ calculate probability sample arises from any particular t . involves set taken samples with known separations between their ages. Since ...

Abstract We study and classify smooth bounded domains in an analytic Riemannian manifold which are critical for the heat content at all times $$t&gt;0$$ t &gt; 0 . do that by first computing variation of content, then showing $$\Omega $$ Ω</mml:...

BACKGROUND Chronic obstructive pulmonary disease (COPD) is a respiratory disorder with increasing prevalence and mortality. It is associated with airway obstruction, increased airway hyper-responsiveness (AHR), and ongoing airway and lung inflammation dominated by CD8 lymphocytes and neutrophils. Single-nucleotide polymorphisms (SNPs) in a disintegrin and metalloprotease 33 (ADAM33) gene have b...
