On Weingarten transformations of hyperbolic nets [PDF]
, 2013 Weingarten transformations which, by definition, preserve the asymptotic lines on smooth surfaces have been studied extensively in classical differential geometry and also play an important role in connection with the modern geometric theory of ...

Hyperboloid offset surface in the architecture and construction industry
Open Engineering, 2019 In this paper the issue of approximation of the hyperboloid offset surface off(S(t, v); d) at distance d by the hyperboloid surface S1(ϕ, v) is considered. The problem of determining various surfaces approximating the hyperboloid offset surface off (S(t,

A New Approach to String Cosmology [PDF]
, 1998 We discuss quotients of Anti-de Sitter (AdS) spacetime by a discrete group in light of the AdS-CFT correspondence. Some quotients describe closed universes which expand from zero volume to a maximum size and then contract. Maldacena's conjecture suggests

Вестник Дагестанского государственного технического университета: Технические науки, 2018 . Objectives This work is a continuation of a series of articles devoted to an analysis of the effect of the utilised second-order surface types on the accuracy of determining earthquake epicentre and hypocentre coordinates. Methods In order to find the

Scalar field theory in Snyder space-time: alternatives [PDF]
, 2010 We construct two types of scalar field theory on Snyder space-time. The first one is based on the natural momenta addition inherent to the coset momentum space. This construction uncovers a non-associative deformation of the Poincar\'e symmetries.

Hyperboloid, instanton, oscillator
Physics Letters B, 2006 We suggest the exactly solvable model of the oscillator on a four-dimensional hyperboloid which interacts with a SU(2) instanton. We calculate its wavefunctions and spectrum.

Design and Performance Evaluation of Asymmetric Hyperboloid Linear Ion Trap [PDF]
Zhipu Xuebao, 2021 Hyperbolic electrode linear ion trap is a good choice as the mass analyzer of miniaturized ion trap mass spectrometer for the reason that it has a compact size and excellent performance. However, ions are ejected from both opposite directions along the x-

Geometric and Kinematic Analysis of Deployable Doubly Ruled Hyperboloids
Megaron, 2017 This paper aims to develop deployable doubly ruled hyperboloid surfaces that can be used in architectural applications. First, the study systematically analyzes the geometric principles of hyperboloids generated by the ruled surface generation method and

Perturbing the Ground Ring of 2-D String Theory
, 1992 We use free field techniques in D=2 string theory to calculate the perturbation of the special state algebras when the cosmologi- cal constant is turned on.
