... Here we shall examine exact solutions to noncommutative gravity, and show that they can give rise to effects which are linear in the noncommutative scale when additional gauge fields are present in the theory. Such ... Lihat dokumen lengkap

... In this article we formulate and prove the analogue of this theorem for SU (N ) symmetric extended Hubbard–Heisenberg chains with pair-hopping term. Recently, the spin and fermionic chains with such symmetry have been ... Lihat dokumen lengkap

... From the first equations of (12) we get by integration a precise determination of a j up to multiplication by a function of u j ; thus the a j part of the solution depends on at most n functions of one variable ... Lihat dokumen lengkap

... Given a compact quantum group Q acting on A, such that the action is implemented by a unitary representation U of the quantum group on H, it is easy to see that the notion of equivariance of the spectral triple with the ... Lihat dokumen lengkap
