Larry Lehman, professor of mathematics, presented a paper entitled “Suborders of Quadratic Polynomials Modulo Primes” at the fall meeting of the MD-DC-VA Section of the Mathematical Association of America, held at Virginia Military Institute in Lexington, Va., in October 2012.
Janusz Konieczny, professor of mathematics, has co-authored a research article, Sn-normal semigroups of partial transformations, published in the journal Algebra Colloquium. The article has been written jointly with two UMW graduates, Sean Droms and Roberto Palomba, and contains the results of undergraduate research that Sean and Roberto did when they were mathematics students at the University of Mary Washington.
Associate Professor and Chair of the Department of Mathematics Keith Mellinger recently had his article “The de Bruijn–Erdős theorem for hypergraphs” published in the journal Designs, Codes and Cryptography. The article was co-authored with mathematicians from the University of Illinois at Chicago, the University of California in San Diego, and Tel Aviv University, Israel.
Three UMW mathematics majors, Morgan Brown, Peter Slattery, and Andrew Cole, traveled to the Shenandoah Undergraduate Mathematics and Statistics conference – SUMS at JMU on Saturday, Sept. 29. The students presented their work completed under the direction of Dr. Leo Lee. Morgan gave a talk “How to Win Every Time” and Peter presented his poster “The Wave Equation in One Dimension”.
Keith E. Mellinger, associate professor and chair of the Department of Mathematics, co-authored the article “Generalized Pellegrino caps ” which appears in the most recent issue of the journal Finite Fields and Their Applications. The journal publishes papers in various applications of finite fields including algebraic coding theory, cryptology, combinatorial design theory, pseudorandom number generation and linear recurring sequences.
