Numerical linear algebra for quaternions — fast, practical, and well‑tested. QuatIca was inspired by the pioneering work in quaternion linear algebra, particularly the QTFM (Quaternion Toolbox for ...

This is a preview. Log in through your library . Abstract For a compact Hausdorff space X, let C(X, H) denote the set of all quaternion-valued functions on X. It is proved that if a real B*-algebra A ...

Inspired by Stark's analytic proof of class number finiteness of a ring of integers in an algebraic number field, we give a new proof of the finiteness of the number of classes of ideals in a maximal ...

Abstract: Vector filtering of signals and images has many applications, but there is little theoretical framework underpinning rather ad-hoc approaches to the development of such filters. In this ...

Abstract: Real-valued wavelets have achieved great success in image denoising due to their sparse representation capability under multi-scale analysis. However, existing real-valued wavelets suffer ...
