Fibrifold
open-in-new
<p>In mathematics, a fibrifold is (roughly) a <a href="/facts/Fiber_space/4g6exYHA">fiber space</a> whose fibers and base spaces are <a href="/facts/Orbifold/KR6dQNzH">orbifolds</a>. They were introduced by <a href="/facts/John_Horton_Conway/g3PA1zoK">John Horton Conway</a>, Olaf Delgado Friedrichs, and Daniel H. Huson et al. (2001), who introduced a system of notation for 3-dimensional fibrifolds and used this to assign names to the 219 affine <a href="/facts/Space_group/2XQx0J7M">space group</a> types. 184 of these are considered reducible, and 35 irreducible. </p>
