Object of study in the present paper are slant and Legendre null curves 3-dimensional Sasaki-like almost contact B-metric manifolds. For examined we express general Frenet frame for which original parameter is distinguished, as well corresponding curvatures, terms structure on manifold. We prove that curvatures a framed curve constants if only specific function considered manifolds constant. fi...

The paper deals with the notion of quasi hemi-slant submersions from Lorentzian para Sasakian manifolds onto Riemannian manifolds. These are generalization and semi-slant submersions. In this paper, we also study geometry leaves distributions which involved in definition submersion. Further, obtain conditions for such to be integrable totally geodesic. Moreover, give characterization theorems p...

Since judgment of geographical slant requires the use of both optical and postural information, such judgments were used to determine whether intermodal relationships affect children’s perception. First, third, and fifth graders made judgments of geographical slant of surfaces depicted in photographs either with or without postural inclination. The results indicate the existence of a linear mec...

for providing the VR{models used in this experiments. The authors thank Pavel Zahorik for comments and suggestions on an earlier draft of this manuscript. We are grateful to Scott Yu for providing the 3D model of our virtual environments lab shown in Fig. 1. Abstract. We have investigated the role of geographical slant in simple navigation and spatial memory tasks, using a computer graphics tow...

In this paper, we study radical transversal lightlike submanifolds and screen slant radical transversal lightlike submanifolds of indefinite para-Sasakian manifolds giving some non-trivial examples of these submanifolds. Integrability conditions of distributions D and RadTM on radical transversal lightlike submanifolds and screen slant radical transversal lightlike submanifolds of indefinite pa...

Purpose Bi-slant submanifolds of S -manifolds are introduced, and some examples these presented. Design/methodology/approach Some properties D i -geodesic -umbilical bi-slant examined. Findings The Riemannian curvature invariants computed, results discussed with the help invariants. Originality/value topic is original, manuscript has not been submitted to any other journal.
