Mass relations in noncommutative geometry revisited

Higgs mass and noncommutative geometry

We show that the description of the electroweak interactions based on noncommutative geometry of a continuous and a discrete space gives no special relations between the Higgs mass and other parameters of the model. We prove that there exists a gauge invariant term, linear in the curvature, which is trivial in the standard differential geometry but nontrivial in the case of the discrete geometr...

چکیده زبان سیستم کاملی ازقوانین است که برای ایجاد ارتباط و تبادل معانی مورد استفاده قرار می گیرد که در رابطه تنگاتنگ با روابط قدرتی افراد می باشد. این رابطه و قدرت افراد می تواند مستقیما در انتخاب ضمایر و سایر ساختارهای زبانی حتی در رفتار افراد تاثیرگذار باشد. در هرجامعه ای ، تقریبا نوعی روابط قدرتی درمیان افراد موجود می باشد و این رابطه درنحوه ی استفاده ی آنها در زبان منعکس می شود. بررسی ای...

Coulomb Potential of a Point Mass in Theta Noncommutative Geometry

Abstract. We investigate the form of the Coulomb potential of a point charge in a noncommutative geometry, using a state of minimal dispersion. We find the deviation of the potential at large distances from the point, distinguishing between coordinate distance and measured distance. Defining the “effective” value of an operator as its expectation value in a minimum dispersion state centered at ...

Duality in Noncommutative Geometry

The structure of spacetime duality and discrete worldsheet symmetries of compactified string theory is examined within the framework of noncommutative geometry. The full noncommutative string spacetime is constructed using the Fröhlich-Gawȩdzki spectral triple which incorporates the vertex operator algebra of the string theory. The duality group appears naturally as a subgroup of the automorphi...
