OCTOBER 24: Jocelyn R. Bell, U. S. Military Academy, will discuss "An Infinite game with
Topological Consequences". Tea, 3:00 p.m., talk 3:45 p.m., Room VC 6-215, Baruch College, Lexington Avenue,
24--25 Street. For more information, contact Aaron Todd,
ABSTRACT: We introduce a two player infinite game for which every metric space has a winning strategy. A space with a winning strategy also has a winning strategy in Gruenhage's W-space game and also satisfies certain covering and separation properties. We discuss some examples and variations on the game.
DECEMBER 12: Candice Price, U. S. Military Academy, gives "A Discussion on Tangle Models:
An Application of Topology". At CCNY, Tea 3:15 p.m. in NAC 8/130, talk 4:00 p.m. in NAC 7/312. For more information,
contact Ralph Kopperman, email@example.com.
ABSTRACT: The tangle model was developed in the 1980's by Professors DeWitt Sumner and Claus Ernst. This model uses the mathematics of tangles to model protein-DNA binding. An n-string tangle is a pair (B,t) where B is a 3-dimensional ball and t is a collection of n non-intersecting curves properly embedded in B. In the tangle model for DNA site-specific recombination, one is required to solve simultaneous equations for unknown tangles which are summands of observed DNA knots and links. This talk will review the tangle model for site specific recombination and discuss another tangle model that utilizes the oriented skein relation for knots.
