The extension of equi-uniformly continuous families of mappings [PDF]

open access: yesPacific Journal of Mathematics, 1985
A subset S of a uniform space X is strongly U-embedded in X if every equi-uniformly continuous real-valued family of functions on S extends to an equi-uniformly continuous real-valued family on X. The relation between strong U-embedding and other uniform extension properties is discussed.

Analyzing spatial inequality in the city of Kerman using spatial statistics [PDF]

open access: yesجغرافیای اجتماعی شهری, 2023
Introduction: Cities, as complex social, geographical, and economic phenomena, also represent a significant spatial phenomenon. In fact, a city is a spatial unit where politics and power are closely intertwined, and cities require policies for their ...

Uniformly continuous set-valued composition operators in the space of total φ-bidimensional variation in the sense of Riesz [PDF]

open access: yesOpuscula Mathematica, 2010
In this paper we prove that if a Nemytskij composition operator, generated by a function of three variables in which the third variable is a function one, maps a suitable large subset of the space of functions of bounded total \(\varphi\)-bidimensional ...

On the Convergence of Multistep Iteration for Uniformly Continuous Φ‐Hemicontractive Mappings [PDF]

open access: yesAbstract and Applied Analysis, 2012
It is shown that the convergence of the multistep iterative process with errors is obtained for uniformly continuous Φ‐hemicontractive mappings in real Banach spaces. We also revise the problems of C. E. Chidume and C. O. Chidume (2005).

An Efficient Algorithm for Zeros of Bounded Generalized Ghi-Quasi-Accretive Maps

open access: yesThe Proceedings of the Nigerian Academy of Science, 2013
This is a research announcement of the following result. Let E be a real normed linear space in which the single-valued normalized duality map is Holder continuous on balls and let A: E → E be a bounded generalized Φ-quasi-accretive map.

On dynamics generated by a uniformly convergent sequence of maps [PDF]

open access: yesTopology and its Applications, 2017
In this paper, we investigate the dynamics of a non-autonomous dynamical system ( X , F ) generated by a uniformly convergent sequence of continuous self maps on X .

ON THE CONTINUITY OF ENTROPY FOR NON-UNIFORMLY EXPANDING MAPS [PDF]

open access: yesEQUADIFF 2003, 2005
It is a difficult problem to verify the existence of these measures for general Dynamical Systems. For Axiom A diffeomorphisms and flows, and uniformly expanding endomorphisms classical results by Sinai, Ruelle and Bowen prove the existence of SRB measures. In this context the continuous variation of the SRB entropy is known.

Adaptive simulation of 3D thermometry maps for interventional MR-guided tumor ablation using Pennes’ bioheat equation and isotherms

open access: yesScientific Reports, 2022
Minimally-invasive thermal ablation procedures have become clinically accepted treatment options for tumors and metastases. Continuous and reliable monitoring of volumetric heat distribution promises to be an important condition for successful outcomes ...
