Welcome to my Userpage
I am a Dutch (Pure) Mathematics student, in my fourth year.
My favourite area at the moment is Topology. Previously it has been Set Theory and Algebra.
My current contributions
Articles:
Intersection of Topologies is Topology
Union of Topologies is not necessarily Topology
Union of Topologies on Singleton or Doubleton is Topology
Product Space is Path-connected iff Factor Spaces are Path-connected
Continuous Mapping to Product Space
Proofs:
T5 Space iff Every Subspace is T4
Product Space is T3 1/2 iff Factor Spaces are T3 1/2
