A converse to this is also true: if V(A) is congruence distributive and A is dualizable, then A has an NU term. An important generalization of the NU term for congruence distributive varieties is the cube term for congruence modular (CM) varieties, and it has been thought that a similar characterization of dualizability for algebras in a CM variety would also hold. We prove that if A omits tame congruence types 1 and 5 (all locally finite CM varieties omit these types) and is dualizable, then A has a cube term. </WRAP> * **November 8**\\ <**html**> <span style="color:blue;font-size:120%"> Colin Reid </span></**html**> (University of Newcastle)\\ **// Totally disconnected, locally compact groups //** \\ \\ <WRAP center box 90%> **//Abstract//**: Totally disconnected, locally compact (t.d.l.c.) groups are a large class of topological groups that arise from a few different sources, for instance as automorphism groups of combinatorial structures, or from the study of isomorphisms between finite**index**subgroups of a given group. Two analogies are that they are like 'discrete groups combined with compact groups' or 'non-Archimedean Lie groups'. A general theory has begun to emerge in recent years, in which we find that the interaction between small-scale and large-scale structure in t.d.l.c. groups is somewhere between the two extremes that these analogies would suggest. I will give a survey of some ways in which these groups arise and a few recent results in the area. </WRAP> * **November 15**\\ <**html**> <span style="color:blue;font-size:120%">Andrew Kelley</span></**html**> (Binghamton University)\\ **//Maximal subgroup growth: current progress and open questions //** \\ \\ <WRAP center box 90%> **//Abstract//**: This is an update on my research on the maximal subgroup growth of certain f.g. groups.

The main focus of this talk will be to give a generalization of Jezek and Kepka's embedding theorem for groupoid modes. We will show that a mode is embeddable into a subreduct of a semimodule over a commutative semiring if and only if it satisfies the so called Szendrei identities. Thus the operations on Szendrei modes can be represented in a particularly nice way. This will involve thinking of operations "additively", that is, taking an n-ary operation and considering it as a sum of n unary operations. </WRAP> * **December 6**\\ <**html**> <span style="color:blue;font-size:120%"> No talk this week </span></**html**>(attend the algebra candidate talk on Friday) \\ ---- ---- * [[http://www.math.binghamton.edu/dept/**AlgebraSem**/**index**.**html**|Pre-2014 semesters]]\\ * [[**seminars**:alge:fall2014]] * [[**seminars**:alge:spring2015]] * [[**seminars**:alge:alge_fall2015]] * [[**seminars**:alge:alge-spring2016]] - The Combinatorics Seminar: 17 Hits
