Redundant constraints in Linear Programminghttps://nforum.ncatlab.org/discussion/7582/2017-01-23T14:00:42+00:002017-01-23T14:36:39+00:00Murat_Aygenhttps://nforum.ncatlab.org/account/1558/
A facet of an n-polytope (having the origin in its interior) is redundant iff its out-normal is within of the polar body spanned by out-normals of the other facets. If this out-normal is on the ...
A facet of an n-polytope (having the origin in its interior) is redundant iff its out-normal is within of the polar body spanned by out-normals of the other facets. If this out-normal is on the boundary of the polar body, then the plane of the redundant facet supports (is tangent to) the n-polytope in question. Are these true?

The identity RP^2 − {0} = μ is as real as the familiar C + {∞} = S^2 where RP^2 is the Projective Plane, 0 is its natural origin, μ is the Mobius Strip, C is the Complex Plane and S^2 is the ...
The identity RP^2 − {0} = μ is as real as the familiar C + {∞} = S^2 where RP^2 is the Projective Plane, 0 is its natural origin, μ is the Mobius Strip, C is the Complex Plane and S^2 is the sphere. I can give a formal proof of this if anyone is interested.
