Canonical forms for unitary congruence and *congruence [PDF]

open access: yesLinear and Multilinear Algebra, 2009
We use methods of the general theory of congruence and *congruence for complex matrices--regularization and cosquares-to determine a unitary congruence canonical form (respectively, a unitary *congruence canonical form) for complex matrices A such that \bar{A}A (respectively, A^2) is normal.

Deductive systems of pseudo-M algebras

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2022
The class of pseudo-M algebras contains pseudo-BCK, pseudo-BCI, pseudo-BCH, pseudo-BE, pseudo-CI algebras and many other algebras of logic. In this paper, the notion of deductive system in a pseudo-M algebra is introduced and its elementary properties ...

Cladistics and Stratigraphy

open access: yesGeosciences, 2023
Using cladistic phylogenies (cladograms) to evaluate stratigraphy (taxon distributions and correlations) necessitates various assumptions that include all of the assumptions built into the cladogram, assuming the cladogram is “correct” and that new taxa ...

Balanced congruences

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2001
If \(\mathfrak{A}\) is an algebra then \(\text{Con}({\mathfrak A})\) is the set of all congruences on \({\mathfrak A}\). If \(\Phi\in \text{Con}({\mathfrak A})\), \(x\in{\mathfrak A}\), then \([x]\Phi=\{t\in{\mathfrak A}\mid (x;t)\in\Phi\}\). If \(M\subseteq{\mathfrak A}\) then \(\Theta(M)\) is the least congruence on \({\mathfrak A}\) containing the ...

Cubic response surface analysis: Investigating asymmetric and level-dependent congruence effects with third-order polynomial models.

open access: yesPsychological methods, 2020
Congruence hypotheses play a major role in many areas of psychology. They refer to, for example, the consequences of person-environment fit, similarity, or self-other agreement. For example, are people psychologically better adjusted when their self-view
