In early October Margaret Readdy is giving a talk in the special session "Geometric Combinatorics" held at the Fall Central Section Meeting of the AMS in Chicago, IL.
At the end of October, Richard Ehrenborg will be giving a talk in the Michigan State University Algebra Seminar.
In mid-November Richard Ehrenborg will be giving a talk in the Indiana University Combinatorics Seminar. Later in November Benjamin Braun will also be giving a talk at the Indiana University Combinatorics Seminar.
Richard Ehrenborg will be talking about the University of Kentucky graduate program in mathematics at the Michigan Undergraduate Mathematics and Midwest Systems Biology Conference.
Nicholas Loehr (College of William and Mary), Gabor Pataki (University of North Carolina), Margaret Readdy, Carla Savage (North Carolina State), and University of Kentucky's Assistant Professor of Statistics Ruriko Yoshida are co-organizing the special session "Combinatorial Enumeration, Optimization, Geometry, and Statistics" at the AMS Fall Southeastern Sectional meeting in Murfreesboro, TN. Carla Savage will be giving a one-hour invited address at the meeting. In the special session graduate student Carlos Nicolas will be giving a talk, along with Benjamin Braun, Margaret Readdy and Ruriko Yoshida .
In Fall 2007 Benjamin Braun will be joining our department as a new Assistant Professor. He received his PhD in 2007 at Washington University in St. Louis under the direction of John Shareshian. Ben has research interests in combinatorics, topology, algebra and geometry.
Graduate student Carlos Nicolas has just been awarded a University of Kentucky Presidential Fellowship.
Carl Lee and his colleagues Margaret Bayer, Lauren Rose and Ed Swartz are organizing a conference in honor of Louis Billera's 65th Birthday June 13-15, 2008. More details to follow.
Carl Lee will be giving a talk at the Geometry Fest in celebration of Ted Bisztriczky's 60th birthday in Budapest, Hungary in June 2007.
Graduate students Patricia Muldoon and Carlos Nicolas will be giving talks at the 3rd annual Graduate Student Combinatorics Conference at the University of Washington in April 2007. The keynote speaker will be Vic Reiner (Minnesota).
In Spring 2007 Margaret Readdy will be giving seminar talks at MIT, Northeastern and Cornell on toric hyperplane arrangements. This is joint work with Richard Ehrenborg and Michael Slone. Richard Ehrenborg will be speaking about this work in the special session "Algebraic and Extremal Combinatorics" at the Spring Southeastern Meeting of the AMS in Davidson, NC in March 2007.
During Spring 2007 Richard Ehrenborg will be giving seminar talks at MIT, Cornell and Northeastern.
Stanley's Gorenstein* lattice conjecture is settled!
Richard Ehrenborg and
Kalle Karu (University of British Columbia)
proved Stanley's conjecture:
the cd-index of a Gorenstein* lattice is coefficientwise
minimized on the Boolean algebra.
Their paper will appear in
Journal of Algebraic Combinatorics.
Earlier work leading up this result was:
Visiting Assistant Professor Edwin O'Shea is an invited speaker at ACCOTA 2006 (Puerto Vallarta, Mexico; December 2006). He will also be giving a four hour tutorial on Groebner basis methods in integer programming at the IMA in January 2007.
Graduate student Patricia Muldoon will be a visiting graduate student at MIT for a week in November 2006.
Richard Ehrenborg and Margaret Readdy are organizing the special session, "Algebraic and Analytic Combinatorics" at the Fall Eastern Meeting of the AMS in Storrs, CT in October 2006.
Graduate student Michael Slone will be a visiting graduate student at MIT for a week in October 2006. He will then attend the Fall Eastern Meeting of the AMS in Storrs, CT, where he will give the talk, "An index for non-regular spheres".
Richard Ehrenborg is giving an invited talk at the special session "Geometric Combinatorics" at the Fall Central Meeting of the AMS in Cincinnati, OH. His talk is titled, "Gorenstein* lattices" and is joint work with Kalle Karu (UBC).
Richard Ehrenborg is giving the first Brandeis-Harvard-MIT-Northeastern joint colloquium of the 2006-07 academic season. His talk title is, "Counting pattern avoiding permutations via integral operators" and is joint work with Sergey Kitaev (Reykjavik) and Peter Perry.
In September 2006 Richard Ehrenborg is giving an invited talk at the Workshop for Geometric and Topological Combinatorics in Madrid, Spain. This is an International Congress of Mathematicians (ICM) satellite conference.
During the academic year 2006-2007 Richard Ehrenborg and Margaret Readdy are both on sabbatical leave at MIT.
Graduate student Carlos Nicolas has proved the empty convex hexagon conjecture of Erdös. This problem has been open since 1977. His paper will appear in Discrete and Computational Geometry.
Effective July 1, 2006, Richard Ehrenborg has been promoted to Full Professor.
Richard Ehrenborg is the Principle Investigator for a National Security Agency Grant (June 2006 - May 2008). His grant is currently supporting summer research by Eric Clark and Michael Slone.
Carl Lee is a Co-PI for ACCLAIM (Appalachian Collaborative Center for Learning, Assessment and Instruction in Mathematics), National Science Foundation grant ESI-0119679 (5 years beginning September 2001; $10,543,250). See www.acclaim-math.org. He is also a Co-PI for AMSP (Appalachian Mathematics Science Partnership), National Science Foundation (5 years beginning October 2002; $22,263,868). See www.appalmsp.org.
