| Description | We will prove the existence of Brownian motion on a specific closed subset T of the unit interval. The set T has certain "regularity" properties that allow the construction to proceed without undue technical difficulties and yet it has infinitely many "gaps" so it gives the flavor of how the argument goes for a general time scale. If time permits, a key partition lemma will be stated and discussed which allows an analogous construction to proceed on a general time scale. |

| Description | In [1], Dimiter Vakarelov describes the concept of a
contact algebra, which was introduced by Dimov and Vakarelov in [2]
to help formalize a notion, championed by Whitehead in [3], of
"contact" between regions in space. Formally, a contact algebra is a
pair A=(B, C), where B=(B,0,1,^,v,~) is a Boolean algebra, and C is
a binary relation on the set B, such that the following
hold: (C1) xCy implies x>0; (C2) xC(yvz) if either xCy or xCz; (C3) xCy implies yCx; (C4) x^y>0 implies xCy. Examples of contact algebras include the algebra of regular closed subsets of a topological space, and the algebra of regular open subsets of a topological space. This kind of "pointless" topology, or "pointless" geometry, has applications in artificial intelligence and knowledge representation, via qualitative spatial reasoning, and represents a fertile area of interaction between classical Boolean algebra, topology and logic.
