Stability of additive functional equation on discrete quantum semigroups
We construct a noncommutative analog of additive functional equations on discrete quantum semigroups and show that this noncommutative functional equation has Hyers-Ulam stability on amenable discrete quantum semigroups. The discrete quantum semigroups that we consider in this paper are in the sense of van Daele, and the amenability is in the sense of Bèdos-Murphy-Tuset. Our main result genera...

Noncommutative geometry is based on an idea that an associative algebra can be regarded as " an algebra of functions on a noncommutative space ". The major contribution to noncommutative geometry was made by A. Connes, who, in particular, analyzed Yang-Mills theories on noncommutative spaces, using important notions that were introduced in his papers (connection, Chern character, etc). It was f...

متن کاملCP - violation from Noncommutative Geometry ∗
If the geometry of space-time is noncommutative, i.e. [x µ , x ν ] = iθ µν , then noncommutative CP violating effects may be manifest at low energies. For a noncommutative scale Λ ≡ θ −1/2 ≤ 2 T eV , CP violation from noncommutative geometry is comparable to that from the Standard Model (SM) alone: the noncommutative contributions to ǫ and ǫ ′ /ǫ in the K-system, and to sin 2β in the B-system, ...
متن کاملInternal Space for the Noncommutative Geometry Standard Model and String
In this note I speculate on connections between the noncommutative geometry approach to the standard model on one side, and the internal space coming from strings on the other. The standard model in noncommutative geometry is described via the spectral action. I argue that an internal noncommutative manifold compactified at the renormalization scale, could give rise to the almost commutative ge...
