In 2006, Alexander proved a result that implies for a Weingarten surface, if is the number of
times a closed geodesic winds around the axis of rotation and is the number of times the …

The considerations of the mechanics of incompressible test bodies moving on spheres are
generalized to the case of λ‐spheres. Both surfaces are examples of Riemannian manifolds …

We propose here a new reference model approximating the actual shape of the Earth. It is
based on λ λ‐spheres as an alternative to the rotational ellipsoids. Relying on quite …

Starting with identifications of the very fundamental geometric characteristics of a Mylar
balloon such as the profile curve, height, volume, arclength, surface area, crimping factor …

In this paper, the very fundamental geometrical characteristics of the Mylar balloon like the
profile curve, height, volume, arclength, surface area, crimping factor, etc. are recognized as …

In 2006, Alexander proved a result that implied for the mylar balloon shape, if n is the
number of times a closed geodesic winds around the axis of rotation and m is the number of …

In the present article, a unifying approach to description of different Heisenberg models (ie,
XY model, isotropic case, easy‐plane, and easy‐axis regimes) for spin distributions on …

The concepts for inflatable deployable structures have been under development and
evaluation for many years. Strangely enough only the Mylar balloon up to now has been …
