UNITARY EQUIVALENCE OF A MATRIX TO ITS TRANSPOSE
Motivated by a problem of Halmos, we obtain a canonical decom- position for complex matrices which are unitarily equivalent to their transpose (UET). Surprisingly, the na¨ove assertion that a matrix
Symmetric matrix representations of truncated Toeplitz operators on finite dimensional spaces
In this paper, we study matrix representations of truncated Toeplitz operators with respect to orthonormal bases which are invariant under a canonical conjugation map. In particular, we determine
COMPLEX SYMMETRIC TRIANGULAR OPERATORS
In this paper we explore complex symmetric operators with eigenvalues. We develop new techniques to give a geometric description of certain complex symmetric triangular operators. This extends a
$C$-normality of rank-one perturbations of normal operators
A bstract . For a separable complex Hilbert space H , we say that a bounded linear operator T acting on H is C -normal, where C is a conjugation on H , if it satisfies CT ∗ TC = TT ∗ . For a normal

Mathematical and physical aspects of complex symmetric operators
TLDR
The main themes of the survey are: the structure of complex symmetric operators, C-selfadjoint extensions of C-symmetric unbounded operators, resolvent estimates, reality of spectrum, bases ofC-orthonormal vectors and conjugate-linear symmetric operator.
Anti- (conjugate) linearity
This is an introduction to antilinear operators. In following Wigner the terminus antilinear is used as it is standard in Physics. Mathematicians prefer to say conjugate linear. By restricting to
Recent Progress on Truncated Toeplitz Operators
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 the field since
Binormal, complex symmetric operators
ABSTRACT In this paper, we describe necessary and sufficient conditions for a binormal or complex symmetric operator to have the other property. Along the way, we find connections to the Duggal and
Symmetry of cyclic weighted shift matrices with pivot-reversible weights
It is proved that every cyclic weighted shift matrix with pivot-reversible weights is unitarily similar to a complex symmetric matrix.

Unitary equivalence to a complex symmetric matrix: a modulus criterion
We develop a procedure for determining whether a square complex matrix is unitarily equivalent to a complex symmetric (i.e., self-transpose) matrix. Our approach has several advantages over existing

We develop several methods, based on the geometric relationship between the eigenspaces of a matrix and its adjoint, for determining whether a square matrix having distinct eigenvalues is unitarily
Some new classes of complex symmetric operators
We say that an operator T E B(H) is complex symmetric if there exists a conjugate-linear, isometric involution C: ℌ→ℌ so that T = CT * C. We prove that binormal operators, operators that are
Unitary equivalence to a truncated Toeplitz operator: analytic symbols
Unlike Toeplitz operators on H2, truncated Toeplitz operators do not have a natural matricial characterization. Consequently, these operators are difficult to study numerically. In this paper we
The Eigenstructure of Complex Symmetric Operators
We discuss several algebraic and analytic aspects of the eigenstructure (si.e., eigenvalues, eigenvectors, and generalized eigenvectors) of complex symmetric operators. In particular, we examine the
Truncated Toeplitz Operators on Finite Dimensional Spaces
In this paper, we study the matrix representations of compressions of Toeplitz operators to the finite dimensional model spaces H2 BH2, where B is a finite Blaschke product. In particular, we

In this paper we investigate operators unitarily equivalent to truncated Toeplitz operators. We show that this class contains certain sums of tensor products of truncated Toeplitz operators. In
