monohedron

Noun

monohedron (plural monohedra or monohedrons)

1. A solid figure with a single continuous surface (face) and no edges, such as a torus or spheroid.
   • This is a reflection of the fact that the monohedron collapses asymptotically to a line (along the w₁-axis) when T -> Tₜ (t -> 0) (Widom, 1975c).1972, Cyril Domb, M. S. Green, Joel Louis Lebowitz, Phase Transitions and Critical Phenomena - Volume 9, page 112
2. A type of hull that has a constant deadrise.
   • The beginner may be confused by old hands learnedly discussing the rival merits of monohedron and warped bottoms, so this matter will be cleared up first.1961, John Teal, Fast Boats; a Guide to Speed Under Sail and Power, page 34
3. A pedion.
   • Then, in the above example, to RPS lying on the equator there corresponds a prism, to those lying outside the equator, a pyramid, and to the polar point, a monohedron.2013, Boris K. Vainshtein, Fundamentals of Crystals, page 185
