The latest Arkansan to head to Washington D.C. is Bob Eslinger. During his sabbatical year
as visiting professor for the Mathematical Association of America Bob will serve as Interim
Director of the Department of Member Services and Programs. Bob and Denise will be living in
Alexandria, Virginia and Bob can be reached at the M.A.A. Headquarters at 1529 Eighteenth
Street, NW, Washington, DC 20036-1385. You can send e-mail to Bob at
Eslinger@alpha.hendrix.edu or firstname.lastname@example.org.
This spring Hendrix students gave undergraduate research presentations at two
conferences: the Hendrix-Rhodes-Sewanee Undergraduate Mathematics Symposium at The
University of the South in Sewanee, Tennessee and the Oklahoma-Arkansas Section Meeting of
the Mathematical Association of America in Weatherford, Oklahoma.
Six students gave presentations at the MAA meeting: Jac Cole, sophomore, "An Introduction
to Elliptical Curves"; Rusty Frizzell, senior, "Computational Geometry and Plane Sweep
Algorithms"; Kevin Hutson, senior, "Conjugacy Classes of Triple Products in Finite Groups";
Wade Satterfield, junior, "Subgroup Diagrams and GAP"; Lars Seme, senior, "Automorphisms
of Hasse Subgroup Diagrams for Cyclic and Dihedral Groups"; and Donna Sword, junior,
"Images and Inverse Images of Iterates of the Line Graph Operators."
Jac, Rusty, Lars and Donna also spoke at the Hendrix-Rhodes-Sewanee meeting where the
hightlight was the grilled veggie burgers.
Computer scientist Rob Hasker has been hired as Bob Eslinger's one year sabbatical
replacement and as Hendrix College's first academic computer scientist.
Rob received his Ph.D. in computer science from the University of Illinois in 1994 and his
undergraduate degree from Wheaton College. Since earning his degree, Rob has worked as a
programming consultant in Champaign, Illinois.
Rob and his wife Jill have just arrived in Conway and are expecting their first child in September.
During this academic year the department will conduct a search to fill a tenure-track position in
Dr. J. Sutherland Frame with Donna Sword.
I recently attended the summer joint mathematics meeting in Burlington, Vermont. While
I was there, I presented some research I began last winter, titled "Images and Inverse Images of
Iterates of the Line Graph Operator."
This trip was very educational for me. I not only learned about mathematics from the talks I
attended, but I was able to speak with mathematicians such as Dr. J. Sutherland Frame about
their past and present research. In addition, through my conversations I gained knowledge of
the many careers open to people in mathematics.
Although the meeting was very beneficial for me, the paper I presented is still incomplete. I
plan to continue my work with line graphs as my senior project. Donna Sword '96
We apologize for the omission of Scott Wagner from our list of 1993-94 seniors in the last
issue of Mathematics At Hendrix. Scott was identified in the photo but not in the article below
the photo. Scott is currently working for Acxiom Corp. in Conway.
Our congratulations to both Scott and Carissa Hurst '94 whose undergraduate research projects
were published in the most recent issue of the Pi Mu Epsilon Journal. The next issue will
contain a paper by Lars Seme '95.
Best wishes are also in order for Dwayne Collins who earlier this summer began a four year term
as Area Chair for the Natural Sciences Area at Hendrix.
From left to right: Tara Leslie, Lars Seme, Rusty Frizzell and Kevin Hutson.
Tara is working for Acxiom in Conway; Lars is in graduate school in mathematics at the
Univ. of Missouri Rolla; Rusty is in graduate school in computer science at the Univ. of Tulsa;
and Kevin is in graduate school in mathematics at Clemson.
For the past two summers Dwayne Collins and David Sutherland have directed a summer
mathematics seminar for interested students who have just completed their freshman year.
One goal is to introduce the students to an area of mathematics which they otherwise would not
study until their junior or senior years. The students also have fun and get to know each other
The summer seminar also gets the students off to an early start doing independent work and it
appears to be a good transition to either undergraduate research projects or Ze'ev Barel's problem
solving seminar which meets during the academic year.
Last summer the students studied elliptical curves and this summer they have been studying
