On Almost Generalized Weakly Symmetric $\alpha$-Cosymplectic Manifolds
Universal Journal of Mathematics and Applications, 2020 In the present paper, we study the notions of an almost generalized weakly symmetric $\alpha$-cosymplectic manifolds and an almost generalized weakly Ricci-symmetrik $\alpha$-cosymplectic manifolds.

Weakly Z-symmetric manifolds [PDF]
Acta Mathematica Hungarica, 2011 We introduce a new kind of Riemannian manifold that includes weakly-, pseudo- and pseudo projective- Ricci symmetric manifolds. The manifold is defined through a generalization of the so called Z tensor; it is named "weakly Z symmetric" and denoted by (WZS)_n.

Silting and Tilting for Weakly Symmetric Algebras [PDF]
Algebras and Representation Theory, 2021 AbstractIf A is a finite-dimensional symmetric algebra, then it is well-known that the only silting complexes in Kb(projA) are the tilting complexes. In this note we investigate to what extent the same can be said for weakly symmetric algebras. On one hand, we show that this holds for all tilting-discrete weakly symmetric algebras.

Weakly symmetric functions on spaces of Lebesgue integrable functions
Karpatsʹkì Matematičnì Publìkacìï, 2022 In this work, we present the notion of a weakly symmetric function. We show that the subset of all weakly symmetric elements of an arbitrary vector space of functions is a vector space.

On weak symmetries of trans-Sasakian manifolds; pp. 213–223 [PDF]
Proceedings of the Estonian Academy of Sciences, 2009 The present paper deals with weakly symmetric and weakly Ricci symmetric trans-Sasakian manifolds. The existence of weakly Ricci symmetric trans-Sasakian manifolds is ensured by an example.

Weakly hyperbolic systems by symmetrization [PDF]
ANNALI SCUOLA NORMALE SUPERIORE - CLASSE DI SCIENZE, 2019 We study hyperbolic first order systems and propose a new method proving Gevrey well posedness, constructing a symmetrizer, motivated by a special Lyapunov function for linear ODE. The proof not only gives a priori estimates straightforward so simply but also clarifies some effects coming from the spectral structures other than the multiplicities of ...

Weakly symmetric pseudo–Riemannian nilmanifolds
Journal of Differential Geometry, 2022 In an earlier paper we developed the classification of weakly symmetric pseudo--riemannian manifolds $G/H$ where $G$ is a semisimple Lie group and $H$ is a reductive subgroup. We derived the classification from the cases where $G$ is compact. As a consequence we obtained the classification of semisimple weakly symmetric manifolds of Lorentz signature $(

On coincidence and fixed-point theorems in fuzzy symmetric spaces [PDF]
Journal of Hyperstructures, 2012 In this paper, common fixed point theorems have been studied in fuzzy symmetric space instead of fuzzy metric space.Using weakly compatibility, property ( E.A.), we have generalized the common fixed point theorems for a pair of weakly compatible self ...

Weakly symmetric biserial algebras [PDF]
Colloquium Mathematicum, 2021 We introduce the class of generalized biserial quiver algebras and prove that they provide a complete classification of all weakly symmetric biserial algebras over an algebraically closed field.
