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 a Topology

Union of Topologies is Not a Topology

Union of Topologies on Singleton or Doubleton is Topology

Product Space is Path-connected iff Factor Spaces are Path-connected

Function to Product Space is Continuous iff Composition with Projections are Continuous

Proofs:

T5 Space iff Every Subspace is T4

Choice Function Exists for All Finite Sets

Product Space is T3.5 iff Factor Spaces are T3.5

Indiscrete Space is Pseudometrizable
