It is clear that this fact may be interpreted as follows: for the observer moving together with information its loss can occur only at the transition to smaller scales, i.e. to greater deformation parameter α. Now we consider the general Information Problem. Note that with the classical Quantum Mech ...

Conjugation coinvariants of quantum matrices
... The conjugation A → g −1 Ag of a complex N × N matrix A by an invertible matrix g induces an action of GL(N, C) on the coordinate algebra C[X ij ] of N × N matrices. The invariant functions with respect to this action are well-known, they are the elements in the C-subalgebra of C[Xij ] that is gener ...

States and Operators in the Spacetime Algebra

An extension to multiparticle systems is introduced, in which separate (commuting) copies of the STA are tak ...
