Dowker Island
Dowker Island is an uninhabited island in Lake Saint Louis, a widening of the Saint Lawrence River south of Montreal Island, Quebec. It is in the municipality of Notre-Dame-de-l'Île-Perrot which intends to preserve its natural state. The island is about a kilometre in length and breadth. Its surface geology is undifferentiated till deposits. It is low-lying, mostly in a 100-year flood area, and contains a muskrat habitat. History Then known as one of the îles Sainte-Geneviève (now Dowker, Madore, and Daoust), the island was granted to governor of Montreal François-Marie Perrot by Jean Talon, in 1672, along with the île Perrot. It was acquired in 1897 by Leslie Rose Dowker (unknown-1945), who shortly afterward became Mayor of Sainte-Anne-du-Bout-de-l'Île, now known as Sainte-Anne-de-Bellevue. It is the site of a ruined stone house as well as a former navigational aid Navigation is a field of study that focuses on the process of monitoring and controlling the movemen ...

Clifford Hugh Dowker
Clifford Hugh Dowker (; March 2, 1912 – October 14, 1982) was a topologist known for his work in point-set topology and also for his contributions in category theory, sheaf theory and knot theory. Biography Clifford Hugh Dowker grew up on a small farm in Western Ontario, Canada. He excelled in mathematics and was paid to teach his math teacher math at his secondary school. He was awarded a scholarship at Western Ontario University, where he got his B.S. in 1933.

Yael Dowker
Yael Naim Dowker (1919–2016) was an English mathematician, prominent especially due to her work in the fields of measure theory, ergodic theory and topological dynamics. Biography Yael Naim (later Dowker) was born in Tel Aviv. She left for the United States to study at Johns Hopkins University in Baltimore, Maryland. In 1941, as a graduate student, she met Clifford Hugh Dowker, a Canadian topologist working as an instructor there. The couple married in 1944.

Dowker Space
In the mathematical field of general topology, a Dowker space is a topological space that is T4 but not countably paracompact. They are named after Clifford Hugh Dowker. The non-trivial task of providing an example of a Dowker space (and therefore also proving their existence as mathematical objects) helped mathematicians better understand the nature and variety of topological spaces. Equivalences Dowker showed, in 1951, the following: If ''X'' is a normal T1 space (that is, a T4 space), then the following are equivalent: * ''X'' is a Dowker space * The product of ''X'' with the unit interval is not normal. * ''X'' is not countably metacompact. Dowker conjectured that there were no Dowker spaces, and the conjecture was not resolved until Mary Ellen Rudin constructed one in 1971. Rudin's counterexample is a very large space (of cardinality \aleph_\omega^). Zoltán Balogh gave the first ZFC construction of a small (cardinality continuum) example, which was more well-behaved ...
