Finger Tip Topologies |
🧾 𝔄𝔟𝔰𝔱𝔯𝔞𝔠𝔱
We sugguest to develop a series of finger tip topologies, generalising the concept of metric, to area, volume, ... . Examples are taken from short exact sequences in some categories of algebra like groups, algebras, ... and from symplectic vector spaces. If it is possible to find axioms for areas, like those for metrics, it should be possible to find axioms for volume such that there are vector spaces with volume. We expect examples from determinants and from pseudo-orthogonal vector spaces, where the topmost one-dimensional vector space in the exterior and Clifford-algebra has such a volume-structure. The special linear groups are their automorphism groups and the traceless linear Lie algebras are their derivation Lie algebras. |

[Loo] | O Loos Symmetric Spaces I + II Benjamin N.Y. [1969] no ISBN We only use the first volume. We generalize his symmetric multiplication from hyperboloids (spheres) to arbitrary elements outside null-cones, this being well-known to the Artin school of mathematics, and this in turn to the complex case of pseudo-Hilbert spaces. One of the main points, following from Loos' definition of a symmetric space, is that instead of studying ℂℂ*-algebras -in quantum mechanics - one should study algebras with an involution ( instead of the *-anti-involution ). | ||
