Admissibility of kneading sequences and structure of Hubbard trees for quadratic polynomials [PDF]

open access: yes, 2008
Hubbard trees are invariant trees connecting the points of the critical orbits of postcritically finite polynomials. Douady and Hubbard \cite{Orsay} introduced these trees and showed that they encode the essential information of Julia sets in a ...

Extreme value theory for moving average processes with light-tailed innovations [PDF]

open access: yes, 2005
We consider stationary infinite moving average processes of the form $Y_n = \sum c_i Z_{n+i}$, where the sum ranges over the integers, (Z_i) is a sequence of iid random variables with ``light tails'' and (c_i) is a sequence of positive and summable ...

New type of difference sequence spaces of fuzzy real numbers

open access: yesMathematical Modelling and Analysis, 2009
In this paper we introduce the natation difference operator Δrn(m ≥ 0, an integer) for studying properties of some sequence spaces. We define the sequence spaces l ∞ F (Δm), cF(Δm), cF o(Δm) and investigate their properties like solid‐ness, convergence ...

SAP--a sequence mapping and analyzing program for long sequence reads alignment and accurate variants discovery. [PDF]

open access: yesPLoS ONE, 2012
The third-generation of sequencing technologies produces sequence reads of 1000 bp or more that may contain high polymorphism information. However, most currently available sequence analysis tools are developed specifically for analyzing short sequence ...

Notes on a General Sequence

open access: yesAnnales Mathematicae Silesianae, 2020
Let {rn}n∈𝕅 be a strictly increasing sequence of nonnegative real numbers satisfying the asymptotic formula rn ~ αβn, where α, β are real numbers with α > 0 and β > 1. In this note we prove some limits that connect this sequence to the number e.

Geometric randomization of real networks with prescribed degree sequence

open access: yesNew Journal of Physics, 2019
We introduce a model for the randomization of complex networks with geometric structure. The geometric randomization (GR) model assumes a homogeneous distribution of the nodes in a hidden similarity space and uses rewirings of the links to find ...

Time-Varying Sequence Model

open access: yesMathematics, 2023
Traditional machine learning sequence models, such as RNN and LSTM, can solve sequential data problems with the use of internal memory states. However, the neuron units and weights are shared at each time step to reduce computational costs, limiting ...

A determinant characterization of moment sequences with finitely many mass-points

open access: yes, 2014
To a sequence (s_n)_{n\ge 0} of real numbers we associate the sequence of Hankel matrices \mathcal H_n=(s_{i+j}),0\le i,j \le n. We prove that if the corresponding sequence of Hankel determinants D_n=\det\mathcal H_n satisfy D_n>0 for ...

Some Double Sequence Spaces of Fuzzy Real Numbers of Paranormed Type

open access: yesJournal of Mathematics, 2013
We study different properties of convergent, null, and bounded double sequence spaces of fuzzy real numbers like completeness, solidness, sequence algebra, symmetricity, convergence-free, and so forth. We prove some inclusion results too.
