+   * **August 27**\\ Organizational meeting
+   * **September 3**\\ <html> <span style="color:blue;font-size:120%">Casey Donoven </span></html>(Binghamton University) \\ **//Automata acting on Fractal Spaces//** \\    \\  <WRAP center box 90%> **//Abstract//**: A self-similar set is a set that is a union of scaled copies of itself.  Through iterated labeling of the $n$ copies, $n^2$ subcopies, and so on, we create a correspondence between infinite sequences over an n letter alphabet and points in the self-similar set.  Automata act naturally on infinite sequence, and I will explore groups of homeomorphisms of semi-similar sets induced by automata.  I will focus on two examples, the unit interval and Julia set associated to the map $z^2+i$.  An important tool in the construction of the automata is the approximation of these self-similar sets as finite graphs.

+   * **September 10**\\ <html> <span style="color:blue;font-size:120%">Matt Evans </span></html>(Binghamton University) \\ **//BCK-algebras and generalized spectral spaces
+//** \\    \\  <WRAP center box 90%> **//Abstract//**: Commutative BCK-algebras are the algebraic semantics of a non-classical logic. Mimicing the
+construction of the spectrum of a commutative ring (or Boolean algebra or distributive lattice),
+we can construct the spectrum of a commutative BCK-algebra.
+A topological space is called *spectral* if it is homeomorphic to the spectrum of some commutative
+ring, and *generalized spectral* if it is homeomorphic to the spectrum of a distributive lattice
+with 0.
+In this talk I will briefly discuss Hochster's characterization of spectral spaces, and then show
+that the spectrum of a commutative BCK-algebra is generalized spectral.

+   * **September 17**\\ <html> <span style="color:blue;font-size:120%">Jonathan Doane </span></html>(Binghamton University) \\ **// Dualizing Kleene Algebras//** \\    \\  <WRAP center box 90%> **//Abstract//**: It is well-known that the class of Boolean algebras is "generated" by
+the two element chain $F<T$ equipped with negation $\neg F:= T$, $\neg
+T:=F$.
+When we include an uncertainty element $F<U<T$, along with negation $\neg
+U: =U$, we generate the class of Kleene algebras.
+Of course, there is a famous correspondence between Boolean algebras and
+Boolean topological spaces, named Stone duality;
+this leads us to wonder if we can somehow represent Kleene algebras by
+topological spaces as well.
+In fact, Stone duality is but an application of a more general theory of
+dual equivalences between categories.
+In this talk, we will utilize this theory to construct a dual equivalence
+between the categories of Kleene algebras
+and certain topological spaces.
