Shock and Vibration, Volume 2021, Issue 1, 2021., 2021 Distributed‐drive electric vehicles constitute an important research direction for the future development of electric vehicles. In this regard, the integrated suspension wheel‐side drive system has considerable development potential because it can address the lack of driving smoothness and the grounding deterioration caused by the excessive unsprung ...

A New Class of Contact Pseudo Framed Manifolds with Applications
International Journal of Mathematics and Mathematical Sciences, Volume 2021, Issue 1, 2021., 2021 In this paper, we introduce a new class of contact pseudo framed (CPF)‐manifolds (M, g, f, λ, ξ) by a real tensor field f of type (1,1), a real function λ such that f3 = λ2f where ξ is its characteristic vector field. We prove in our main Theorem 2 that M admits a closed 2‐form Ω if λ is constant.

On Distance in Some Finite Planes and Graphs Arising from Those Planes
Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021 In this paper, affine and projective graphs are obtained from affine and projective planes of order pr by accepting a line as a path. Some properties of these affine and projective graphs are investigated. Moreover, a definition of distance is given in the affine and projective planes of order pr and, with the help of this distance definition, the ...

Certain Class of Almost α‐Cosymplectic Manifolds
Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021 This paper concerned with almost α‐cosymplectic manifolds satisfying conformally flat condition. Firstly, we investigate Kaehler integral submanifolds of almost α‐cosymplectic manifolds. Next, we study conformally flat almost α‐cosymplectic manifolds of dim ≥ 5 whose integral submanifolds are Kaehler.

Approximate Lie Symmetry Conditions of Autoparallels and Geodesics
Abstract and Applied Analysis, Volume 2020, Issue 1, 2020., 2020 This paper is devoted to the study of approximate Lie point symmetries of general autoparallel systems. The significance of such systems is that they characterize the equations of motion of a Riemannian space under an affine parametrization. In particular, we formulate the first‐order symmetry determining equations based on geometric requirements and ...

The geometry of GL(2,q) in translation planes of even order q2
International Journal of Mathematics and Mathematical Sciences, 1978 In this article we show the following: Let π be a translation plane of even order q2 that admits GL(2,q) as a collineation group. Then π is either Desarguesian, Hall or Ott-Schaeffer.

Hypersurfaces in a conformally flat space with curvature collineation
International Journal of Mathematics and Mathematical Sciences, 1991 We classify the shape operators of Einstein and pseudo Einstein hypersurfaces in a conformally flat space with a symmetry called curvature collineation. We solve the fundamental problem of finding all possible forms of non-diagonalizable shape operators.

ON THE DEFINITION OF MATTER COLLINEATIONS [PDF]
Modern Physics Letters A, 2009 It is shown that when the stress–energy tensor of a spacetime is diagonal and is written in the mixed form, its collineations admit infinite dimensional Lie algebras except possibly in the case when the tensor depends on all the spacetime coordinates. The result can be extended for more general second rank tensors.

Fuzzy collineations of 3-dimensional fuzzy projective space from 4-dimensional fuzzy vector space
AIMS MathematicsIn this paper, the fuzzy counterparts of the collineations defined in classical projective spaces are defined in a 3-dimensional fuzzy projective space derived from a 4-dimensional fuzzy vector space. The properties of fuzzy projective space $ (\lambda, \
