I wrote this essay during my 5th Semester at the ILLC Amsterdam for the course Philosophy of Logic (Lecture). The essay is made available at Overleaf: A Topological Approach to Infinite Disjunctions. I have been influenced for the topic of this essay by the course Topology, Logic and Learning (Lecture) by Alexandru Baltag. This essay can both be regarded as part of Philosophy of Mathematics and Logic and of Formal Epistemology.
