Rethinking the link between matter and geometry [PDF]
Physical Review D, 2018 In the present manuscript, I examine an intriguing relation at the classical level between general relativity and a theory where matter couples uniquely multiplicatively to geometry in the Lagrangian density. Interestingly, the gravitational constant $G$ is replaced by a novel fundamental constant, whose value is not tied to any classical phenomenon ...

On canonical triangulations of once-punctured torus bundles and two-bridge link complements [PDF]
, 2005 We prove the hyperbolization theorem for punctured torus bundles and two-bridge link complements by decomposing them into ideal tetrahedra which are then given hyperbolic structures, following Rivin's volume maximization principle.Comment: This is the ...

Acta Crystallographica Section E, 2012 The title compound, [Hg5Br10(C7H8N2O)2]n, contains two μ3-bridging Br atoms, six μ2-bridging Br atoms and two terminal Br atoms. One HgII atom, lying on an inversion center, adopts a distorted octahedral geometry defined by six Br atoms.

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.

PRE-SERVICE TEACHERS PERFORMANCE IN GEOMETRY IN THE COLLEGES OF EDUCATION, GHANA
JETEN, 2022 Studies indicate that geometry enables pre-service teachers to link mapping objects in the classroom to real-life situations. Additionally, studies indicated that the proficiency development of the participants is a challenge.

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.

2-(5-Bromo-2-methylphenyl)propan-2-ol
Acta Crystallographica Section E, 2010 The title compound, C10H13BrO, crystallizes with four independent molecules of similar geometry in the asymmetric unit. The crystal packing is stabilized by intermolecular O—H...O hydrogen bonds, which link the molecules into tetramers.
