Janusz Konieczny, professor of mathematics, gave an invited talk, “The Commuting Graph of the Symmetric Inverse Semigroup,” at the Analysis, Logic and Physics Seminar at Virginia Commonwealth University.
Keith Mellinger, Associate Professor and Chair of the Department of Mathematics, recently saw his co-authored research article Embedding cycles in finite planes published in the Electronic Journal of Combinatorics. The article addresses graph cycles in planes, a topic that has been connected to certain soft-decision decoding algorithms for error-correcting codes.
Assistant Professor of Mathematics, Jangwoon “Leo” Lee, recently presented “Domain Decomposition Methods for Solving Stochastic PDEs” at the annual US-Korea Conference (UKC 2013) in New Jersey. In addition to attending many research talks at the conference, Dr. Lee chaired an applied mathematics session.
Keith Mellinger, Associate Professor and Chair of the Department of Mathematics, recently traveled to two conferences to present various results of his research. First, was the 2nd Annual Conference for the Exchange of Mathematical Ideas, a conference he helped to organize, held at the University of Northern Iowa. There he spoke about Blocking Semiovals and Their Applications to Cryptography. He also traveled to London, England, for the 24th British Combinatorial Conference where he delivered the presentation titled Minimal Kakeya Sets.
Assistant Professor of Mathematics, Jangwoon “Leo” Lee, traveled to Iowa State University in Ames, Iowa, last weekend to deliver an invited talk at the Spring Central Sectional Meeting of the American Mathematical Society. His talk was titled Discretization of Stochastic Optimal Control Problems by the h x p Version of the Stochastic Galerkin FEM.
Associate Professor and Chair of Mathematics Keith Mellinger recently attended the Mathematical Association of America‘s regional meeting held at Salisbury University. At the meeting, Mellinger presented Eigentriads – a musical offering in which he discussed eigenvectors, a topic found in any undergraduate course in linear algebra, and an amusing relationship they have with diminished and augmented triads.
Larry Lehman, professor of mathematics, published the article “Suborder Polynomials Modulo Primes” in the February 2013 issue of JP Journal of Algebra, Number Theory and Applications. This article relates patterns in recursively defined sequences to the roots over finite fields of a certain class of polynomials.
