A Series of Unfortunate Events the plot of "The Grim Grotto", the eleventh book. The Baudelaire orphans are named after Charles Baudelaire; Violet's name also comes from the T.S. Eliot's poem "The Waste Land", specifically its verses concerning the "violet hour," and Sunny and Klaus take their first names from Claus and Sunny von Bülow, while Mr. Poe is a reference to Edgar Allan Poe (his sons are named Edgar and Albert). In the seventh installment, "The Vile Village," Count Olaf's disguise, Detective Dupin, is an allusion to C. Auguste Dupin, a fictional detective created by Edgar Allan Poe. Isadora and Duncan Quagmire are named
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
