  • On S-Topological Groups

    On S-Topological Groups

    Mathematica Moravica Vol. 18-2 (2014), 35–44 On s-Topological Groups Muhammad Siddique Bosan, Moiz ud Din Khan and Ljubiša D.R. Kočinac∗) Abstract. In this paper we study the class of s-topological groups and a wider class of S-topological groups which are defined by us- ing semi-open sets and semi-continuity introduced by N. Levine. It is shown that these groups form a generalization of topological groups, and that they are different from several distinct notions of semitopolog- ical groups which appear in the literature. Counterexamples are given to strengthen these concepts. Some basic results and applications of s- and S-topological groups are presented. Similarities with and differ- ences from topological groups are investigated. 1. Introduction If a set is endowed with algebraic and topological structures, then it is natural to consider and investigate interplay between these two structures. The most natural way for such a study is to require algebraic operations to be continuous. It is the case in investigation of topological groups: the multi- plication mapping and the inverse mapping are continuous. Similar situation is with topological rings, topological vector spaces and so on. However, it is also natural to see what will happen if some of algebraic operations sat- isfy certain weaker forms of continuity. Such a study in connection with topological groups started in the 1930s and 1950s and led to investigation of semitopological groups (the multiplication mapping is separately con- tinuous), paratopological groups (the multiplication is jointly continuous), quasi-topological groups (which are semitopological groups with continu- ous inverse mapping).

Arhangel’skii, M. Huˇsek Abstract. The main results concern commutativity of Hewitt-Nachbin realcompactifica- tion or Dieudonn´ecompletion with products of topological groups. It is shown that for every topological group G that is not Dieudonn´ecomplete one can find a Dieudonn´e complete group H such that the Dieudonn´ecompletion of G × H is not a topological group containing G×H as a subgroup. Using Korovin’s construction of Gδ-dense orbits, we present some examples showing that some results on topological groups are not valid for semitopological groups.

    J. K-Theory 11 (2013), 527–547 ©2013 ISOPP doi:10.1017/is012011011jkt203 Quillen’s work in algebraic K-theory by DANIEL R. GRAYSON Abstract We survey the genesis and development of higher algebraic K-theory by Daniel Quillen. Key Words: higher algebraic K-theory, Quillen. Mathematics Subject Classification 2010: 19D99. Introduction This paper1 is dedicated to the memory of Daniel Quillen. In it, we examine his brilliant discovery of higher algebraic K-theory, including its roots in and genesis from topological K-theory and ideas connected with the proof of the Adams conjecture, and his development of the field into a complete theory in just a few short years. We provide a few references to further developments, including motivic cohomology. Quillen’s main work on algebraic K-theory appears in the following papers: [65, 59, 62, 60, 61, 63, 55, 57, 64]. There are also the papers [34, 36], which are presentations of Quillen’s results based on hand-written notes of his and on communications with him, with perhaps one simplification and several inaccuracies added by the author. Further details of the plus-construction, presented briefly in [57], appear in [7, pp. 84–88] and in [77]. Quillen’s work on Adams operations in higher algebraic K-theory is exposed by Hiller in [45, sections 1-5]. Useful surveys of K-theory and related topics include [81, 46, 38, 39, 67] and any chapter in Handbook of K-theory [27].

    An Introduction to Topological Groups

    An Introduction to Topological Groups by Dylan Spivak A project submitted to the Department of Mathematical Sciences in conformity with the requirements for Math 4301 (Honours Seminar) Lakehead University Thunder Bay, Ontario, Canada copyright c (2015) Dylan Spivak Abstract This project is a survey of topological groups. Specifically, our goal is to investigate properties and examples of locally compact topological groups. Our project is structured as follows. In Chapter 2, we review the basics of topology and group theory that will be needed to understand topological groups. This summary in- cludes definitions and examples of topologies and topological spaces, continuity, the prod- uct topology, homeomorphism, compactness and local compactness, normal subgroups and quotient groups. In Chapter 3, we discuss semitopological groups. This includes the left and right translations of a group G, the left and right embeddings of G, products of semitopological groups and compact semitopological groups. Chapter 4 is on topological groups, here we discuss subgroups, quotient groups, and products of topological groups. We end the project with locally compact topological groups; here we investigate compact- ness and local compactness in topological groups. An important class of locally compact topological groups are groups of matrices. These structures are important in physics, we go over some of their basic properties. i Acknowledgements I would like to thank my supervisor Dr. Monica Ilie for taking the time to meet with me every week, for carefully editing all of my proofs, and for working with me during the summer. Her kindness and experience made this project a pleasure to work on. I would also like to thank Dr.

Introduction The purpose of this note is to refine and improve upon some of the recent advances made by Bouziad on the question of when a semitopological group is in fact a topological group. Recall that a semitopological group (paratopological group) is a group endowed with a topology for which multiplication is separately (jointly) continuous. Research on this question possibly began in [13] when Montgomery showed that each completely metrizable semitopological group is a paratopological group. Later in 1957 Ellis showed that each locally compact semitopological group is in fact a topological group (see [5,6]).

The study of the behavior of fluids dates back to Archimedes, who discovered that any body immersed in a liquid receives a vertical upward thrust, which is equal to the weight of the displaced liquid. Later, Leonardo Da Vinci was fascinated by turbulence, another key feature of fluid flows. But the first advances in the analysis of fluids date from the beginning of the eighteenth century with the birth of differential calculus, which revolutionized the mathematical understanding of the movement of bodies, solids, and fluids. The discovery of the governing equations for the motion of fluids goes back to Euler in 1757; further progress in the nineteenth century was due to Navier and later Stokes, who explored the role of viscosity. In the middle of the twenti- eth century, Kolmogorov’s theory of tur- bulence was another turning point, as it set future directions in the exploration of fluids. More complex geophysical models incorporating temperature, salinity, and ro- tation appeared subsequently, and they play a role in weather prediction and climate modeling. Nowadays, the field of mathematical fluid dynamics is one of the key areas of partial differential equations and has been the fo- cus of extensive research over the years.

Introduction Andrei Suslin (1950–2018) was both friend and mentor to us. This article dis- cusses some of his many mathematical achievements, focusing on the role he played in shaping aspects of algebra and algebraic geometry. We mention some of the many important results Andrei proved in his career, proceeding more or less chronolog- ically beginning with Serre’s Conjecture proved by Andrei in 1976 (and simul- taneously by Daniel Quillen). As the reader will quickly ascertain, this article does not do justice to the many mathematicians who contributed to algebraic K- theory and related subjects in recent decades. In particular, work of Hyman Bass, Alexander Be˘ılinson, Spencer Bloch, Alexander Grothendieck, Daniel Quillen, Jean- Pierre Serre, and Christophe Soul`e strongly influenced Andrei’s mathematics and the mathematical developments we discuss.

The classical J-homomorphism was introduced under a different name in 1942 by Whitehead [Whi42] in order to study homotopy groups of the spheres.
