On discrete Painlevé equations associated with the affine Weyl group E_7 [PDF]

Open Communications in Nonlinear Mathematical Physics
We derive a class of discrete Painlev\'e equations associated with the affine Weyl group E$_7^{(1)}$. The method used is the deautonomisation of a QRT mapping belonging to the canonical form VI (according to the classification of said mappings).

Rotationally Symmetric Lacunary Functions and Products of Centered Polygonal Lacunary Functions

Fractal and Fractional, 2020
This work builds upon previous studies of centered polygonal lacunary functions by presenting proofs of theorems showing how rotational and dihedral mirror symmetry manifest in these lacunary functions at the modulus level.

Martin Heidegger and the Being and Time of Black Holes [PDF]

Философия и космология, 2020
Scientific narratives about cosmology often present black holes as frightening objects of both creation and destruction, the centres of which are concealed behind event horizons.

On nonsupersymmetric $\BC^4/\BZ_N$, tachyons, terminal singularities and flips

, 2010
We investigate nonsupersymmetric $\BC^4/\BZ_N$ orbifold singularities using their description in terms of the string worldsheet conformal field theory and its close relation with the toric geometry description of these singularities and their possible ...

Is a pole type singularity an alternative to inflation? [PDF]

, 2018
In this paper, we apply a method of reducing the dynamics of FRW cosmological models with the barotropic form of the equation of state to the dynamical system of the Newtonian type to detect the finite scale factor singularities and the finite-time ...

Economías singulares [PDF]

Lecturas de Economía, 2010
En este artículo pretendemos mostrar que le conjunto de las economías singulares, si bien pequeño desde el punto de vista de la topología y/o desde el punto de vista de la teoría de la medida, tiene importantes efectos en el desarrollo de los regímenes económicos.

Quantum Singularities in Static Spacetimes

, 2011
We review the mathematical framework necessary to understand the physical content of quantum singularities in static spacetimes. We present many examples of classical singular spacetimes and study their singularities by using wave packets satisfying ...

The Geometry of Black Hole singularities [PDF]

, 2014
Recent results show that important singularities in General Relativity can be naturally described in terms of finite and invariant canonical geometric objects. Consequently, one can write field equations which are equivalent to Einstein's at non-singular

Evaluating the Utility of Paired Tumor and Germline Targeted DNA Sequencing for Pediatric Oncology Patients: A Single Institution Report

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objective To evaluate the diagnostic yield and utility of universal paired tumor–normal multigene panel sequencing in newly diagnosed pediatric solid and central nervous system (CNS) tumor patients and to compare the detection of germline pathogenic/likely pathogenic variants (PV/LPVs) against established clinical referral criteria for cancer ...
