WHICH TOPOLOGIES HAVE IMMEDIATE PREDECESSORS IN THE POSET OF HAUSDORFF TOPOLOGIES?
(UNIV HOUSTON, 2009)
We study which topology have an immediate predecessor in the poset of Sigma(2) of Hausdorff topologies on set X. We show that certain classes of H-closed topologies, do have predecessors. and we give examples of second ...
Function spaces of coercivity for the fractional Laplacian in spaces of homogeneous type
(Duke University Press, 2019-05)
We combine dyadic analysis through Haar type wavelets defined on Christ´s families of generalized cubes, and Lax-Milgram theorem, in order to prove existence of Green´s functions for fractional Laplacians on some function ...

The QUEST for Brazilian space research
(2006-05-22)
This paper describes how QUEST 1 (QUaternion ESTimator algorithm) influenced Brazilian space research activities. Indeed, we present a short survey paper on researches in attitude determination and propagation in Brazil ...
Homotopies of maps of suspended real and complex projective spaces and their cohomotopy groups
(2021-04-15)
We describe the set [X,Y] of path-components of pointed mapping spaces M⁎(X,Y), where X is chosen to be the reduced kth suspension EkFPm of a projective space FPm and Y is a sphere Sn or FPn for F=R,C, the fields of real ...
National aeronautics and space administration on IGTV: multimodal discourses of space
(2022)
This study employed critical analysis of multimodal texts to examine how NASA utilizes multiple modes like text, visuals, font, and sound to communicate space on a modern multimodal platform—Instagram. Four main themes ...
Multilinear H older-type inequalities on Lorentz sequence spaces
(Universidad de San Andrés. Departamento de Matemáticas y Ciencias, 2008-07)
We establish Hölder type inequalities for Lorentz sequence spaces and their duals. In order to achieve these and some related inequalities, we study diagonal multilinear forms in general sequence spaces, and obtain estimates ...
Coorbit spaces of symbols for square integrable families of operators
(Editura Acad. Romani, 2016)
The aim of this article is to provide a unified construction of coorbit spaces of symbols for the calculus associated to a square-integrable family of bounded Hilbert space operators, going far beyond the group theoretic ...
