Noncommutative topological theories of gravity [PDF]
Physical Review D, 2003 The possibility of noncommutative topological gravity arising in the same manner as Yang-Mills theory is explored. We use the Seiberg-Witten map to construct such a theory based on a SL(2,C) complex connection, from which the Euler characteristic and the signature invariant are obtained.

Noncommutative Koszul algebras from combinatorial topology [PDF]
Journal für die reine und angewandte Mathematik (Crelles Journal), 2010 Associated to any uniform finite layered graph Gamma there is a noncommutative graded quadratic algebra A(Gamma) given by a construction due to Gelfand, Retakh, Serconek and Wilson. It is natural to ask when these algebras are Koszul. Unfortunately, a mistake in the literature states that all such algebras are Koszul.

Topological Charge of Noncommutative ADHM Instanton [PDF]
Modern Physics Letters A, 2003 We analytically calculate the topological charge of general noncommutative U (N) instantons using the Corrigan's identity and find that the result is exactly the instanton number k, which appears in the noncommutative ADHM construction as the dimension of the vector space V. This result coincides with the corresponding fact in the commutative case.

Noncommutative Topological Dynamics. II [PDF]
Transactions of the American Mathematical Society, 1984 This part deals with almost periodic and weakly mixing C ∗ {C^ \ast } -flows, and with disjointness and weak disjointness of C ∗ {C^ \ast } -flows (flows on C ∗ {C^ \ast } -algebras).

Quantum metric spaces of quantum maps
Universal Journal of Mathematics and Applications, 2018 We show that any quantum family of quantum maps from a noncommutative space to a compact quantum metric space has a canonical quantum pseudo-metric structure.

Topological charges of noncommutative soliton [PDF]
Physics Letters B, 2001 The noncommutative soliton is characterized by the use of the projection operators in non-commutative space. By using the close relation with the K-theory of $C^*$-algebra, we consider the variations of projection operators along the commutative directions and identify their topological charges.

TOPOLOGICAL STRINGS ON NONCOMMUTATIVE MANIFOLDS [PDF]
International Journal of Geometric Methods in Modern Physics, 2004 We identify a deformation of the N=2 supersymmetric sigma model on a Calabi–Yau manifold X which has the same effect on B-branes as a noncommutative deformation of X. We show that for hyperkähler X such deformations allow one to interpolate continuously between the A-model and the B-model.
