We discuss in some generality aspects of noncommutative differential geometry associated with reality conditions and with differential calculi. We then describe the differential calculus based on derivations as generalization of vector fields, and we show its relations with quantum mechanics. Finally we formulate a general theory of connections in this framework. 1
SU(n)connections and noncommutative differential geometry
 J. Geom. Phys
, 1998
"... We study the noncommutative differential geometry of the algebra of endomorphisms of any SU(n)vector bundle. We show that ordinary connections on such SU(n)vector bundle can be interpreted in a natural way as a noncommutative 1form on this algebra for the differential calculus based on derivation ..."

We study the noncommutative differential geometry of the algebra of endomorphisms of any SU(n)vector bundle. We show that ordinary connections on such SU(n)vector bundle can be interpreted in a natural way as a noncommutative 1form on this algebra for the differential calculus based on derivations. We interpret the Lie algebra of derivations of the algebra of endomorphisms as a Lie algebroid. Then we look at noncommutative connections as generalizations of these usual connections.

. In commutative differential geometry the FrolicherNijenhuis bracket computes all kinds of curvatures and obstructions to integrability. In [1] the FrolicherNijenhuis bracket was developed for universal differential forms of noncommutative algebras, and several applications were given. In this paper this bracket and the FrolicherNijenhuis calculus will be developed for several kinds of differential graded algebras based on derivations, which were introduced by [6].

Connections on Central Bimodules

We define and study the theory of derivationbased connections on a recently introduced class of bimodules over an algebra which reduces to the category of modules whenever the algebra is commutative.

We define and study the theory of derivationbased connections on a recently introduced class of bimodules over an algebra which reduces to the category of modules whenever the algebra is commutative. This theory contains, in particular, a noncommutative generalization of linear connections. We also discuss the different noncommutative versions of differential forms based on derivations. Then we investigate reality conditions and a noncommutative generalization of pseudoriemannian structures.

In commutative differential geometry the FrölicherNijenhuis bracket computes all kinds of curvatures and obstructions to integrability. In [3] the FrölicherNijenhuis bracket was developped for universal differential forms of noncommutative algebras, and several applications were given. In this paper this bracket and the FrölicherNijenhuis calculus will be developped for several kinds of differential graded algebras based on derivations, which were indroduced by [6].
