Studies in History and Philosophy of Science, 2021 Dasgupta (2015) has recently put forward a novel argument, which he calls the 'curvature argument', that aims to show that Galilean spacetime is not an ideal setting for our classical theory of motion. This paper examines the curvature argument and argues that it is not sound.

Review on the aerodynamics of intermediate compressor duct
Journal of Mechanical Engineering and Sciences, 2020 In a turbofan engine, the air is brought from the low to the high-pressure compressor through an intermediate compressor duct. Weight and design space limitations impel to its design as an S-shaped. Despite it, the intermediate duct has to guide the flow

New curvature tensors along Riemannian submersions [PDF]
arXiv, 2020 In 1966, B. O'Neill [The fundamental equations of a submersion, Michigan Math. J., Volume 13, Issue 4 (1966), 459-469.] obtained some fundamental equations and curvature relations between the total space, the base space and the fibres of a submersion.

, 2020 Preference for curved over sharp-angled contours is a well-known effect. However, it was quite unexplored during the 20th century and only a few sporadic studies dealt with it. Nevertheless, there has been renewed interest in this topic over the past two decades.

Coordinate-free study of Finsler spaces of $H_{p}$-scalar curvature [PDF]
arXiv, 2018 The aim of the present paper is to provide an \emph{intrinsic} investigation of special Finsler spaces of $H_{p}$-scalar curvature and of $H_{p}\,$-constant curvature. Characterizations of such spaces are shown. Sufficient condition for Finsler space of $H_{p}$-scalar curvature to be of perpendicular scalar curvature is investigated.

Mean Curvature Driven Ricci Flow [PDF]
arXiv, 2009 We obtain the evolution equations for the Riemann tensor, the Ricci tensor and the scalar curvature induced by the mean curvature flow. The evolution for the scalar curvature is similar to the Ricci flow, however, negative, rather than positive, curvature is preserved. Our results are valid in any dimension.

On the geometry and topology of manifolds of positive bi-Ricci curvature [PDF]
arXiv, 1997 We introduce some new curvature quantities such as conformal Ricci curvature and bi-Ricci curvature and extend the classical Myers theorem under these new curvature conditions. Moreover, we are able to obtain the Myers type theorem for minimal submanifolds in ambient manifolds with positive bi-Ricci curvature.
