Towards The Moduli Space of Extended Partial Isometries
Abstract Partial Isometries are important constructs that help give nontrivial solutions once a simple solution is known. We generalize this notion to Extended Partial Isometries and include operators which have right inverses but no left inverses (or vice versa). We find a large class of such operators and show the moduli space to contain the Hilbert Scheme of Points. Further, we apply this te...
متن کاملPartial Isometries: a Survey
We survey the main results characterizing partial isometries in C∗algebras and tripotents in JB∗-triples obtained in terms of regularity, conorm, quadratic-conorm, and the geometric structure of the underlying Banach spaces.
متن کاملQUANTUM n-SPACE AS A QUOTIENT OF CLASSICAL n-SPACE
The prime and primitive spectra of Oq(k), the multiparameter quantized coordinate ring of affine n-space over an algebraically closed field k, are shown to be topological quotients of the corresponding classical spectra, specO(kn) and maxO(kn) ≈ kn, provided the multiplicative group generated by the entries of q avoids −1.
متن کاملPartial Orders on Partial Isometries
This paper studies three natural pre-orders of increasing generality on the set of all completely non-unitary partial isometries with equal defect indices. We show that the problem of determining when one partial isometry is less than another with respect to these pre-orders is equivalent to the existence of a bounded (or isometric) multiplier between two natural reproducing kernel Hilbert spac...
متن کاملThe Space of Essential Matrices as a Riemannian Quotient Manifold
The essential matrix, which encodes the epipolar constraint between points in two projective views, is a cornerstone of modern computer vision. Previous works have proposed different characterizations of the space of essential matrices as a Riemannian manifold. However, they either do not consider the symmetric role played by the two views or do not fully take into account the geometric peculia...
