A Trine University mathematics student will present two mathematics colloquia in Wells
Theater on the university campus.
Jacob Roeder of Granger, Indiana, will speak Thursday, Oct. 14, on “Graph Pebbling,”
and Thursday, Oct. 28, on “Algebraically Defined Graphs.” Both events begin at 4 p.m.,
and are free and open to the public.
The topics come from research Roeder assisted in as part of a summer research experience
Graph pebbling is a mathematical game played on an undirected graph with no loops
or multiple edges. An (a,b) graph pebbling game involves two players who alternate
making moves in the following manner: removing a pebbles from the a vertex and adding
b pebbles to an adjacent vertex, with a greater than b. The first player having no
available move loses the game.
