In the quest for squares in plane continua

Cristina Villanueva-Segovia ⟨cristina@im.unam.mx⟩

Abstract:

In this talk we will be looking at conditions on a plane continuum X (not necessarily locally connected) that guarantee the existence of four points in X that are the vertices of a Euclidean Square (in which case we say that X admits an inscribed square). In particular we show that ‘‘certain type of square inscription´´ is generic among continua that separate the plane. The motivation of this work comes from the square peg problem: Does every Jordan curve admits an inscribed square?
