Evolutoids and pedaloids of frontals on timelike surfaces
Open Mathematics, 2023 In this article, we define evolutoids and pedaloids of frontals on timelike surfaces in Minkowski 3-space. The evolutoids of frontals on timelike surfaces are not only the generalization of evolutoids of curves in the Minkowski plane but also the ...

On the Timelike Circular Surface and Singularities in Minkowski 3-Space
Axioms, 2023 In this paper, we have parameterized a timelike (Tlike) circular surface (CIsurface) and have obtained its geometric properties, including striction curves, singularities, Gaussian and mean curvatures.

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.

Quantum Black Holes and (Re)Solution of the Singularity
Universe, 2021 Classical general relativity predicts the occurrence of spacetime singularities under very general conditions. Starting from the idea that the spacetime geometry must be described by suitable states in the complete quantum theory of matter and gravity ...

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 discrete Painlevé equations associated with the affine Weyl group E_7 [PDF]
Open Communications in Nonlinear Mathematical PhysicsWe 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).

Naked singularities are not singular in distorted gravity
Nuclear Physics B, 2014 We compute the Zero Point Energy (ZPE) induced by a naked singularity with the help of a reformulation of the Wheeler-DeWitt equation. A variational approach is used for the calculation with Gaussian Trial Wave Functionals. The one loop contribution of the graviton to the ZPE is extracted keeping under control the UltraViolet divergences by means of a ...

Bare singulars and singularity in Turkish [PDF]
Linguistics and Philosophy, 2021 AbstractThis paper explores the semantics of bare singulars in Turkish, which are unmarked for number in form, as in English, but can behave like both singular and plural terms, unlike in English. While they behave like singular terms as case-marked arguments, they are interpreted number neutrally in non-case-marked argument positions, the existential ...
