Complex Symmetric Partial Isometries [PDF]

Journal of Functional Analysis, 2009
An operator $T \in B(\h)$ is complex symmetric if there exists a conjugate-linear, isometric involution $C:\h\to\h$ so that $T = CT^*C$. We provide a concrete description of all complex symmetric partial isometries.

Partial Isometries and EP Elements in Rings With Involution [PDF]

Electronic Journal of Linear Algebra, 2009
If R is a ring with involution, and a† is the Moore-Penrose inverse of a ∈ R, thenthe element a is called: EP, if aa† = a†a; partial isometry, if a∗ = a†; star-dagger, if a∗a† = a†a∗.
