mathematics, a space form is a complete Riemannian manifold M of constant sectional curvature K. The three most fundamental examples are Euclidean n-space, the...

In geometric topology, the spherical space form conjecture (now a theorem) states that a finite group acting on the 3-sphere is conjugate to a group of...

Unique Forms of Continuity in Space (Italian: Forme uniche della continuità nello spazio) is a 1913 bronze Futurist sculpture by Umberto Boccioni. It is...

space form is said to be a spherical space form if the curvature is positive, a Euclidean space form if the curvature is zero, and a hyperbolic space...

In mathematics, a bilinear form is a bilinear map V × V → K on a vector space V (the elements of which are called vectors) over a field K (the elements...

wider sense, the form is the way something happens. Form may also refer to: Form (document), a document (printed or electronic) with spaces in which to write...
