C. Auguste Dupin of their around-the-world adventure. A Pierre Dupin appears in Universal Pictures' 1932 horror-mystery film "Murders in the Rue Morgue". "The Mystery of Marie Roget" was also filmed in 1942. Dupin (played by Joseph Cotten) is a character in the 1951 Fletcher Markle film "The Man with a Cloak". Dupin's true identity is revealed at the end of the film to be Poe himself. In the comic series "Batman Confidential", the creation of Batman's crime-solving super-computer which is linked to Interpol, FBI, and CIA databases is introduced. Commonly known as the "Bat Computer," it is originally nicknamed "Dupin," after Batman's "hero."
Dupin cyclide "R" are a 3-dimensional vectors, and "A" and "B" are constants. Families of cyclides give rise to various cyclidic coordinate geometries. In Maxime Bôcher's 1891 dissertation, "Ueber die Reihenentwickelungen der Potentialtheorie", it was shown that the Laplace equation in three variables can be solved using separation of variables in 17 conformally distinct quadric and cyclidic coordinate geometries. Many other cyclidic geometries can be obtained by studying R-separation of variables for the Laplace equation. Dupin cyclide In mathematics, a Dupin cyclide or cyclide of Dupin is any geometric inversion of a standard torus, cylinder or double cone. In particular, these latter
