The algebra of observables in noncommutative deformation theory
Eriksen, Eivind; Siqveland, Arvid (Journal article; Peer reviewed, 2019)We consider the algebra O(M) of observables and the (formally) versal morphism η : A → O(M) defined by the noncommutative deformation functor DefM of a family M = {M1, . . . , Mr} of right modules over an associative ... -
Geometry of noncommutative algebras
Eriksen, Eivind; Siqveland, Arvid (Journal article; Peer reviewed, 2011)There has been several attempts to generalize commutative algebraic geometry to the noncommutative situation. Localizations with good properties rarely exists for noncommutative algebras, and this makes a direct generalization ...
