Locally conformal symplectic structures and their generalizations from the point of view of Lie algebroids

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2004
We study locally conformal symplectic structures and their generalizations from the point of view of transitive Lie algebroids. To consider l.c.s.

Reduced contragredient Lie algebras and PC Lie algebras

open access: yesOsaka Journal of Mathematics, 2016
The first aim of this paper is to show that any finite-dimensional reductive Lie algebra and its finite-dimensional completely reducible representation can be embedded into some PC Lie algebra. The second aim is to find the structure of a PC Lie algebra.

On the Terwilliger Algebra of the Group Association Scheme of the Symmetric Group Sym(7) $\text{Sym}(7)$

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT Terwilliger algebras are finite‐dimensional semisimple algebras that were first introduced by Paul Terwilliger in 1992 in studies of association schemes and distance‐regular graphs. The Terwilliger algebras of the conjugacy class association schemes of the symmetric groups Sym(n) $\text{Sym}(n)$, for 3≀n≀6 $3\le n\le 6$, have been studied and ...

Who Knows Best What the Next Year Will Hold for You? The Validity of Direct and Personality‐based Predictions of Future Life Experiences Across Different Perceivers

open access: yesEuropean Journal of Personality, EarlyView., 2020
Abstract This study explored the validity of person judgements by targets and their acquaintances (‘informants’) in longitudinally predicting a broad range of psychologically meaningful life experiences. Judgements were gathered from four sources (targets, N = 189; and three types of informants, N = 1352), and their relative predictive validity was ...

A Sharper Ramsey Theorem for Constrained Drawings

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Given a graph G $G$ and a collection C ${\mathscr{C}}$ of subsets of Rd ${{\mathbb{R}}}^{d}$ indexed by the subsets of vertices of G $G$, a constrained drawing of G $G$ is a drawing where each edge is drawn inside some set from C ${\mathscr{C}}$, in such a way that nonadjacent edges are drawn in sets with disjoint indices.
