Mathematical work
One of Hindman's early contributions was his dissertation for his Ph.D. thesis,
conducted in collaboration with W. W. Comfort and S. Negrepontis. Their research explored conditions for defining F'-spaces and investigated concepts such as weakly Lindelöf spaces and
P-space
In the mathematical field of topology, there are various notions of a ''P''-space and of a ''p''-space.
Generic use
The expression ''P-space'' might be used generically to denote a topological space satisfying some given and previously introduc ...
