Carolina Dynamics Symposium 2017


We're looking forward to seeing you at this year's Carolina Dynamics Symposium! Please see below for some additional information about the conference.

Friday's talk

There will be a colloquium style talk by Nic Ormes (University of Denver) at 4pm on April 21st in Fretwell 128. This talk will be accessible to advanced undergraduates, and all are welcome to attend! Starting at 3pm we will have Tea and light refreshments in the Math Lounge (located on the 3rd floor of Fretwell).

Title: Directed Graphs, Symbolic Dynamics and the Nonnegative Inverse Eigenvalue Problem

Abstract: The Nonnegative Inverse Eigenvalue Problem (NIEP) asks for necessary and sufficient conditions for a list of complex numbers to be the eigenvalues of a matrix with nonnegative entries. This problem was posed in 1949 by H. R. Suleimanova and remains open today. In this talk we will discuss variants of this problem which have been solved in papers of Boyle-Handelman (1991) and Kim-Ormes-Roush (2000). The talk will focus on the connections between nonnegative matrices, directed graphs and symbolic dynamics which were critical to these results.


The conference banquet will be held in room 112 of the Cone Center at 6pm on Saturday, April 22nd. If you plan to attend but did not rsvp "yes" in the conference registration form, then please let us know as soon as possible and not later than April 17th.

UNCC Mathematics Department Lounge

The Mathematics Department Lounge will serve as a the venue for several events over the course of the weekend, including tea time on Friday afternoon. The room number is Fretwell 370D (on the third floor of Fretwell building), and there are building maps on each floor of the building. From the main entrance to the math department on the third floor of Fretwell, go left, then take your first left, and continue straight into the room.

WIFI access on campus at UNCC

If your home institution has eduroam, then you are welcome to use that network on campus. In this case, you will login using your institution's credentials.
