چکیده
The noncommutative extension of a dynamical 2-dimensional space-time is given and some of its properties discussed. Wick rotation to euclidean signature yields a surface which has as commutative limit the doughnut but in a singular limit in which the radius of the hole tends to zero.

A large–scale smoothed–out model of the universe ignores small–scale inhomogeneities, but the averaged effects of those inhomogeneities may alter both observational and dynamical relations at the larger scale. This article discusses these effects, and comments briefly on the relation to gravitational entropy.

We present a classical formalism describing two-time physics with background gauge fields. The formalism has an irreducible version that can be used as a starting point for the construction of a quantized two-time physics theory with a minimum length in a noncommutative Lorentz-covariant space-time.
