We study the maximal algebraic degree of principal ortho-compressions of linear operators that constitute spatial matricial numerical ranges of higher order. We demonstrate (amongst other things) that for a (possibly unbounded) operator L L on a Hilb

We explore the relationship between local and global reducibility of spaces of nilpotent matrices. By local reducibility we mean that small subspaces of a given irreducible linear space L ⊆ M n ( C ) are reducible. One of our main results is that f

Let $\mathcal{H}$ be a complex, separable Hilbert space, and $\mathcal{B}(\mathcal{H})$ denote the set of all bounded linear operators on $\mathcal{H}$. Given an orthogonal projection $P \in \mathcal{B}(\mathcal{H})$ and an operator $D \in \mathcal{B

Let n ∈ N , and consider C n equipped with the standard inner product. Let A ⊆ L ( C n ) be a unital algebra and P ∈ L ( C n ) be an orthogonal projection. The space L : = P ⊥ A | ran P is said to be an off-diagonal corner of A , and L is sai
