A note on the singular value decomposition of (skew-)involutory and (skew-)coninvolutory matrices
, 2019 The singular values $\sigma >1$ of an $n \times n$ involutory matrix $A$ appear in pairs $(\sigma, \frac{1}{\sigma}),$ while the singular values $\sigma = 1$ may appear in pairs $(1,1)$ or by themselves.

Hoffman-Wielandt type inequality for block companion matrices of certain matrix polynomials
, 2022 Matrix polynomials with unitary/doubly stochastic coefficients form the subject matter of this manuscript. We prove that if $P(\lambda)$ is a quadratic matrix polynomial whose coefficients are either unitary matrices or doubly stochastic matrices, then ...

Similarity and consimilarity of hyper-dual generalized quaternions [PDF]
The aim of this paper is to investigate similarity and consimilarity of hyper-dual generalized quaternions and their matrices. For this purpose, we give different conjugates according to the generalized quaternionic units i,j,k.

Angles, Majorization, Wielandt Inequality and Applications [PDF]
, 2013 In this thesis we revisit two classical definitions of angle in an inner product space: real-part angle and Hermitian angle. Special attention is paid to Krein’s inequality and its analogue.
