Idempotent vector spaces and their linear transformations
This article extends topics about linear algebra and operator theoretic linear transformations on complex vector spaces to those on bicomplex spaces.

Linear relations and the Kronecker canonical form [PDF]
We show that the Kronecker canonical form (which is a canonical decomposition for pairs of matrices) is the representation of a linear relation in a finite dimensional space. This provides a new geometric view upon the Kronecker canonical form.

An overview of cyclicity in Dirichlet-type spaces in the unit ball
We shall discuss the characterization of cyclicity of polynomials in Dirichlet-type spaces in the Euclidean unit ball of Cn ${\mathbb{C}}^{n}$ which remains an open problem.

Perturbation Bounds For Isotropic Invariant Subspaces Of Skew-Hamiltonian Matrices
We investigate the behavior of isotropic invariant subspaces of skew-Hamiltonian matrices under structured perturbations. It is shown that finding a nearby subspace is equivalent to solving a certain quadratic matrix equation.

Some results on b-AM-compact operators
We show that for positive operator B : E → E on Banach lattices, if there exists a positive operator S : E → E such that:1.SB ≤ BS;2.S is quasinilpotent at some x0 > 0; 3.S dominates a non-zero b-AM-compact operator, then B has a non-trivial closed ...
