Symmetric Functions in Noncommuting Variables
Mercedes H. Rosas, Bruce E. Sagan
Consider the algebra Q<<x_1,x_2,...>> of formal power series in countably many noncommuting variables over the rationals. The subalgebra Pi(x_1,x_2,...) of symmetric functions in n…

Maximal Independent Sets In Graphs With At Most r Cycles
Chee Ying Goh, Khee Meng Koh, Bruce E. Sagan +1
We find the maximum number of maximal independent sets in two families of graphs: all graphs with vertices and at most cycles, and all such graphs that are also connected.…
