https://doi.org/10.1007/978-1-349-25417-0s conjecture for the closure of homogenous polynomial ideals on the Drury–Arveson space. Finally, we consider the relation between the relative position of two essentially normal projections and the . homology elements defined for them.

Non-negative Self-adjoint Extensions in Rigged Hilbert Space,rove the existence and uniqueness results for extremal non-negative biextensions in terms of the Kreĭn–von Neumann and Friedrichs extensions of a given non-negative symmetric operator. Further, the connections between positive boundary triplets and non-negative self-adjoint bi-extensions are presented

An Analogue of the Spectral Mapping Theorem for Condition Spectrum,. In general these two sets are different. We define functions . (that take small values for small values of ϵ) and prove that . The classical Spectral Mapping Theorem is shown as a special case of this result. We give estimates for these functions in some special cases and finally illustrate the results by numerical computations.
