Which weighted composition operators are complex symmetric?
Stephan Ramon Garcia, Christopher Hammond
Recent work by several authors has revealed the existence of many unexpected classes of normal weighted composition operators. On the other hand, it is known that every normal oper…
Recent progress on truncated Toeplitz operators
Stephan Ramon Garcia, William T. Ross
This paper is a survey on the emerging theory of truncated Toeplitz operators. We begin with a brief introduction to the subject and then highlight the many recent developments in…
A method for generating realistic correlation matrices
Johanna Hardin, Stephan Ramon Garcia, David Golan
Simulating sample correlation matrices is important in many areas of statistics. Approaches such as generating Gaussian data and finding their sample correlation matrix or generati…
On the closure of the complex symmetric operators: compact operators and weighted shifts
Stephan Ramon Garcia, Daniel E. Poore
We study the closure of the set of all complex symmetric operators on a separable, infinite-dimensional, complex Hilbert space. Among other things, we prove that…
Unitary equivalence to a complex symmetric matrix: low dimensions
Stephan Ramon Garcia, Daniel E. Poore, James E. Tener
A matrix $T \in \M_n(\C)$ is \emph{UECSM} if it is unitarily equivalent to a complex symmetric (i.e., self-transpose) matrix. We develop several techniques for studying this proper…
