Abstract. Let H be the mean curvature vector of an n-dimensional submanifold in a Riemannian manifold. The functional ℋ = ∫‖H‖n is called the total mean curvature functional. In this paper, we present ...

The objective of this paper is to achieve the inequality for Ricci curvature of a contact CR-warped product submanifold isometrically immersed in a generalized Sasakian space form admitting a ...

Daily-life foldable items, such as popup tents, the curved origami sculptures exhibited in the Museum of Modern Art of New York, overstrained bicycle wheels, released bilayered microrings and strained ...

A March 9 Facebook post (direct link, archive link) features an image of the Earth taken from outer space. “The first ‘photo’ of the curvature was published on April Fools Day,” reads the text in the ...
