Index theory in geometry and physics
… class on the sphere defined by the Toeplitz operators in the Bergman space of the unit ball. The second and third paper uses regularization of index formulas in cyclic cohomology to produce analytic formulas for the degree of Hölder continuous mappings. In the second paper Toeplitz operators …

Gluing Z₂-Harmonic Spinors on 3-Manifolds
… analysis of degenerating families of elliptic operators. Part II: This part studies the deformation theory of Z₂-harmonic spinors. For a fixed smooth singular set, the deformation theory of 𝑍₂-harmonic spinors is obstructed by infinite-dimensional cokernel of the semi-Fredholm Z₂-Dirac …

The Symbol of a Markov Semimartingale
… As examples the solutions of stochastic differential equations are considered. The symbol is then used to derive a quick approach to the semimartingale characteristics as well as the generator of the process under consideration. Finally we give some examples of how our methods work for …
