O que (quem) é P2-irreducible manifold - definição
P2-irreducible manifold
3-MANIFOLD THAT IS IRREDUCIBLE AND CONTAINS NO 2-SIDED REAL PROJECTIVE PLANE
P-irreducible; P²-irreducible; P2-irreducible
In mathematics, a P2-irreducible manifold is a 3-manifold that is irreducible and contains no 2-sided \mathbb RP^2 (real projective plane). An orientable manifold is P2-irreducible if and only if it is irreducible..
P2 (storage media)
STORAGE MEDIA FORMAT
P2 Card; DVCPRO P2
P2 (P2 is a short form for "Professional Plug-In") is a professional digital recording solid-state memory storage media format introduced by Panasonic in 2004, and especially tailored to electronic news-gathering (ENG) applications. It features tapeless (non-linear) recording of DV, DVCPRO, DVCPRO25, DVCPRO50, DVCPRO-HD, or AVC-Intra streams on a solid-state flash memory.
G2 manifold
SEVEN-DIMENSIONAL RIEMANNIAN MANIFOLD WITH HOLONOMY GROUP CONTAINED IN G2
Joyce manifold; G2-manifold
In differential geometry, a G2 manifold is a seven-dimensional Riemannian manifold with holonomy group contained in G2. The group G_2 is one of the five exceptional simple Lie groups.
