Compact phase space, cosmological constant, discrete time [PDF]
, 2015 We study the quantization of geometry in the presence of a cosmological constant, using a discretiza- tion with constant-curvature simplices. Phase space turns out to be compact and the Hilbert space finite dimensional for each link.

Geometry of biperiodic alternating links
Journal of the London Mathematical Society, 2018 A biperiodic alternating link has an alternating quotient link in the thickened torus. In this paper, we focus on semi-regular links, a class of biperiodic alternating links whose hyperbolic structure can be immediately determined from a corresponding Euclidean tiling. Consequently, we determine the exact volumes of semi-regular links.

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

Numerical study on the behavior of link-to-column connections in eccentrically braced frames [PDF]
Numerical Methods in Civil Engineering, 2014 Geometry of eccentrically braced frames (EBFs) in some cases causes the connection of link beam to the column. The details of such conditions should be studied carefully due to the full plastic rotation in the link beam. In this research, the behavior of

Investigation and analysis of the linear dimensions of the flexible manipulator section in the process of tilting [PDF]
E3S Web of Conferences, 2023 A feature of the functioning of such a device is a change in the position of each of the sections. The study of the peculiarities of changing the position of the link is an important task.

(3-Hydroxy-2-{[1-(2-oxidophenyl)ethylidene]amino-κ2O,N}propanoato-κO1)diphenyltin(IV)
Acta Crystallographica Section E, 2010 In the title compound, [Sn(C6H5)2(C11H11NO4)], the tin(IV) atom is penta-coordinated in a distorted trigonal-bipyramidal SnC2NO2 geometry. In the crystal structure, intermolecular O—H...O hydrogen bonds link the molecules into centrosymmetric ...

Refilling meridians in a genus 2 handlebody complement [PDF]
, 2008 Suppose a genus two handlebody is removed from a 3-manifold M and then a single meridian of the handlebody is restored. The result is a knot or link complement in M and it is natural to ask whether geometric properties of the link complement say ...

Vacuum Solutions of Classical Gravity on Cyclic Groups from Noncommutative Geometry [PDF]
, 2001 Based on the observation that the moduli of a link variable on a cyclic group modify Connes' distance on this group, we construct several action functionals for this link variable within the framework of noncommutative geometry.
