**"Hands-on Dynamical Systems"**

**Dr. Karen Keene, North Carolina State University**

In her talk, Dr. Keene will offer a hands on way for students to be introduced to the notion of solutions for dynamical systems. Participants in the colloquium will use pipe cleaners to construct an understanding of what a solution to a dynamical system looks like. Then specialized technology will move students into a more formal understanding.

Come prepared to listen, talk, and work in a fun area of mathematics.

**"Classical and Generalized Iteration"**

**Dr. Jesse Feller, Kutztown University**

The study of holomorphic dynamical systems (discrete time) is a relatively new area of study involving the repeated composition of a single function f(z) in a process called iteration. Thus we are studying the convergence of the sequence of functions f^{n}(z) = (f ◦ f ◦ ... ◦ f)(z) (n times). We will discover the concept of periodic points and classify them into the three categories of attracting, repelling, or neutral. Most of our examples have dynamical properties that are easily understood. Other examples have dynamical properties that are called chaotic due to their unpredictability. We will take a look at several computer generated images of the important Julia and filled Julia sets for several examples.

Some mathematicians studying dynamics focus on composing a different function at each step of the iteration process where the function is chosen from a family according to some probability distribution. This is called random iteration. We will learn about a few recent results in this area regarding the probability that a random iteration ends up “close” to an attracting periodic point.

**"Factor Pair Latin Squares: Be There or Be Square"**

**Dr. James Hammer, Cedar Crest College**

Sudoku has risen in popularity over the past few years. The rules are simple, yet the solutions are often less than trivial. Mathematically, these puzzles are interesting in their own right. This talk will use the idea of a Sudoku puzzle to define a new kind of n x n array. Further, we will aim to prove some necessary (and on occasion sufficient) conditions for the existence of these arrays. To that end, we define a Latin square of order n as an n x n array where every row and every column contain every symbol 1,2,...,n exactly once. We say (a,b) is an ordered factor pair of the integer n if n = a x b. An (a,b)-Sudoku Latin square is a Latin square where in addition to each row and column containing every symbol exactly once, each a x b rectangle also contains every symbol exactly once when the n x n array is tiled with a x b rectangles in the natural way. A factor pair Latin square of order n (denoted FPLS(n)) is an (a,b)-Sudoku Latin square for every factor pair (a,b) of n. This talk will mainly be concerned with the existence of such designs as well as related problems to such designs.
