The real line is complete, but the open unit interval (which is topologically the same, i.e. homeomorphic to the real line) is not complete. In this talk, we will survey some\u00a0<em>topological<\/em>\u00a0notions of completeness. One strong notion of completeness is complete metrizability; a space\u00a0X is completely metrizable if it is homeomorphic to a complete metric space. On the weaker end, a space is called Baire if the intersection\u00a0of countably many dense open sets is dense. There is an interesting spectrum of topological properties in between. Such properties arise from generalizing convergence of sequences, from topological games, and from domain theory.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker:\u00a0Dr. Lynne Yengulalp from Wake Forest University (invited by Will Brian) Date and Time:\u00a0Friday, February 25, 2022, 11:00-12:00 in person.
