Thomas Dry Howie Carillon
No full textThe Thomas Dry Howie Carillon in the Thomas Dry Howie Tower at The Citadel Military College is a traditional carillon of 59 bells. The carillon was installed in 1955 with bells that were cast by the van Bergen Bell Foundry (Heiligerlee, NL). In 2004, 25 bells were recast by Les Fils de Georges Paccard (Annecy, FR)
Semigroups of order-decreasing transformations
No full textLet X be a totally ordered set and consider the semigroups of orderdecreasing (increasing) full (partial, partial one-to-one) transformations of X. In this
Thesis the study of order-increasing full (partial, partial one-to-one) transformations
has been reduced to that of order-decreasing full (partial, partial one-to-one)
transformations and the study of order-decreasing partial transformations to that of
order-decreasing full transformations for both the finite and infinite cases.
For the finite order-decreasing full (partial one-to-one) transformation
semigroups, we obtain results analogous to Howie (1971) and Howie and McFadden
(1990) concerning products of idempotents (quasi-idempotents), and concerning
combinatorial and rank properties. By contrast with the semigroups of order-preserving
transformations and the full transformation semigroup, the semigroups of orderdecreasing
full (partial one-to-one) transformations and their Rees quotient semigroups
are not regular. They are, however, abundant (type A) semigroups in the sense of
Fountain (1982,1979). An explicit characterisation of the minimum semilattice
congruence on the finite semigroups of order-decreasing transformations and their Rees
quotient semigroups is obtained.
If X is an infinite chain then the semigroup S of order-decreasing full
transformations need not be abundant. A necessary and sufficient condition on X is
obtained for S to be abundant. By contrast, for every chain X the semigroup of
order-decreasing partial one-to-one transformations is type A.
The ranks of the nilpotent subsemigroups of the finite semigroups of orderdecreasing
full (partial one-to-one) transformations have been investigated
Howie Hunter Interview, December 9, 2013
No full textHowie Hunter discusses his time as a student at the University of Montana. He describes working briefly for the U.S. Forest Service before taking a position at a local forest products company, where he worked until retiring in 1988. Hunter also talks about his time in the military during World War Two. He tells a story about being in a prisoner of war camp and how his association with the University of Montana helped him befriend a German guard. Hunter discusses witnessing the Holocaust, as well as traveling to Germany decades after the war.https://scholarworks.umt.edu/collegeofforestry_oralhistory/1008/thumbnail.jp

On the local-indicability cohen–lyndon theorem
No full textFor a group H and a subset X of H, we let HX denote the set {hxh?1 | h ? H, x ? X}, and when X is a free-generating set of H, we say that the set HX is a Whitehead subset of H. For a group F and an element r of F, we say that r is Cohen–Lyndon aspherical in F if F{r} is a Whitehead subset of the subgroup of F that is generated by F{r}. In 1963, Cohen and Lyndon (D. E. Cohen and R. C. Lyndon, Free bases for normal subgroups of free groups, Trans. Amer. Math. Soc. 108 (1963), 526–537) independently showed that in each free group each non-trivial element is Cohen–Lyndon aspherical. Their proof used the celebrated induction method devised by Magnus in 1930 to study one-relator groups. In 1987, Edjvet and Howie (M. Edjvet and J. Howie, A Cohen–Lyndon theorem for free products of locally indicable groups, J. Pure Appl. Algebra 45 (1987), 41–44) showed that if A and B are locally indicable groups, then each cyclically reduced element of A*B that does not lie in A ? B is Cohen–Lyndon aspherical in A*B. Their proof used the original Cohen–Lyndon theorem. Using Bass–Serre theory, the original Cohen–Lyndon theorem and the Edjvet–Howie theorem, one can deduce the local-indicability Cohen–Lyndon theorem: if F is a locally indicable group and T is an F-tree with trivial edge stabilisers, then each element of F that fixes no vertex of T is Cohen–Lyndon aspherical in F. Conversely, by Bass–Serre theory, the original Cohen–Lyndon theorem and the Edjvet–Howie theorem are immediate consequences of the local-indicability Cohen–Lyndon theorem. In this paper we give a detailed review of a Bass–Serre theoretical form of Howie induction and arrange the arguments of Edjvet and Howie into a Howie-inductive proof of the local-indicability Cohen–Lyndon theorem that uses neither Magnus induction nor the original Cohen–Lyndon theorem. We conclude with a review of some standard applications of Cohen–Lyndon asphericit

Non-orientable surface-plus-one-relation groups
No full textRecently Dicks–Linnell determined the L2-Betti numbers of the orientable surface-plus-one-relation groups, and their arguments involved some results that were obtained topologically by Hempel and Howie. Using algebraic arguments, we now extend all these results of Hempel and Howie to a larger class of two-relator groups, and we then apply the extended results to determine the L2-Betti numbers of the non-orientable surface-plus-one-relation group
