  • A Topology for any Group as a Quotient of a Free Group (I) — Department of Mathematics and Computer Science
    Free Group I filed under Topology Seminar Christine Bussman SLU What Topology Seminar When Tue Mar 19 2002 from 03 30 PM to 04 30 PM Where RH 142 Add event to calendar vCal iCal Abstract Any free group can by given a non discrete Hausdorff topology by a method exhibited by Marshall Hall drawing on results by K Iwasawa Any group can be expressed as the quotient of a free group by a normal subgroup of that free group so the topology which Hall imposes on the free group also provides a quotient topology on the selected group We will first follow Hall s construction of the topology for the free group Then we will relate group theoretical properties of that normal subgroup of the free group to properties of the quotient topology Document Actions iCalendar vCalendar Send this Print this February 2016 February Su Mo Tu We Th Fr Sa 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 Upcoming Events Geometry Topology Seminar Tue Feb 16 2016 Orbifolds 04 Kimberly Druschel Math CS Club Wed Feb 17

  • Computational Complexity of Knot Theory and 3-Manifold Algorithms — Department of Mathematics and Computer Science
    to 05 00 PM Where RH 128 Add event to calendar vCal iCal Abstract Among the most fundamental questions in mathematics is whether you can decide if two objects are the same In 1961 Haken constructed an algorithm to decide if a knot is unknotted Recent work of Hass Lagarias and others has analyzed this algorithm to decide its computational complexity Their results show that the unknot can be recognized in exponential time and also that the unknot recognition problem is both in NP and co NP A number of other problems in knot theory and 3 manifold topology are also known to be solvable These include deciding if two knots are isotopic 3 sphere recognition and for some classes of 3 manifolds deciding if two manifolds are homeomorphic The computational complexity of these algorithms and others will be discussed Also practical implementations of these algorithms and the software package REGINA will be talked about Document Actions iCalendar vCalendar Send this Print this February 2016 February Su Mo Tu We Th Fr Sa 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

  • Quotient Spaces of Linear Solvable Group Actions — Department of Mathematics and Computer Science
    space and let G be a subgroup of GL V In general the quotient space V G of G orbits can be as bad as you want it to be There are some fairly broad classes of solvable groups G however for which V G admits a useful though incomplete description In this talk I will use a number of examples to illustrate a method that obtains the following i A finite partition of V into invariant algebraic subsets W ii For each W an explicit algebraic subset S of W that is a cross section for the orbits in W iii A fiber bundle structure P W S for which P 1 v Gv v in S Specific theorems assert that this method can be carried out for certain classes of solvable groups If it seems desirable then some indication of the applicability of these results to harmonic analysis may be given I will finish by discussing the difficulties in carrying this method out for other classes of solvable groups Document Actions iCalendar vCalendar Send this Print this February 2016 February Su Mo Tu We Th Fr Sa 1 2 3 4 5 6 7 8 9 10 11
