The optimal conformal projection for pan-European mapping [PDF]
Geodetski Vestnik, 2020 There is an increasing need for pan-European spatial datasets, mainly to support the common European Union policies. This has inevitably raised demands for adopting pan-European cartographic projections to visualize the spatial data.

A note on surfaces with prescribed oriented Euclidean Gauss map
International Journal of Mathematics and Mathematical Sciences, 2005 We present another proof of a theorem due to Hoffman and Osserman in Euclidean space concerning the determination of a conformal immersion by its Gauss map.

Conformal Maps, Biharmonic Maps, and the Warped Product
Mathematics, 2016 In this paper we study some properties of conformal maps between equidimensional manifolds, we construct new example of non-harmonic biharmonic maps and we characterize the biharmonicity of some maps on the warped product manifolds.

Einstein and Jordan frame correspondence in quantum cosmology: expansion-collapse duality
European Physical Journal C: Particles and Fields, 2023 The conformal correspondence between FLRW universes in the Einstein and Jordan frames allows for an expansion-collapse duality – an always expanding Einstein frame universe can have a dual Jordan frame description that is contracting forever.

Conformal smectics and their many metrics [PDF]
, 2012 We establish that equally spaced smectic configurations enjoy an infinite-dimensional conformal symmetry and show that there is a natural map between them and null hypersurfaces in maximally symmetric spacetimes.

The 't Hooft Model As A Hologram [PDF]
, 2009 We consider the 3d dual of 1+1 dimensional large-N_c QCD with quarks in the fundamental representation, also known as the 't Hooft model. 't Hooft solved this model by deriving a Schroedinger equation for the wavefunction of a parton inside the meson. In

Correlation functions at the bulk point singularity from the gravitational eikonal S-matrix
Journal of High Energy Physics, 2019 The bulk point singularity limit of conformal correlation functions in Lorentzian signature acts as a microscope to look into local bulk physics in AdS.

Proposed single-zone map projection system for Turkey
Reports on Geodesy and Geoinformatics, 2022 The coordinate base of the maps or sheets produced is the Universal Transversal Mercator (UTM) conformal projection, and it is not possible to work in a single coordinate system in Turkey.
