String excitation by initial singularity of inflation
Journal of High Energy Physics, 2021 We discuss excitation of string oscillation modes by an initial singularity of inflation. The initial singularity of inflation is known to occur with a finite Hubble parameter, which is generally lower than the string scale, and hence it is not clear ...

Weak (1,1) bounds for oscillatory singular integrals
Duke Mathematical Journal, 1987 Theorem. For any polynomial P: \({\mathbb{R}}^ n\times {\mathbb{R}}^ n\to {\mathbb{R}}\) and any Calderón-Zygmund kernel K, the operator \(Tf(x)=p.v.\int e^{iP(x,y)}K(x-y)f(y)dy\) is of weak type (1,1) with a bound depending only on \(\| K\|_{CZ}\) and the degree of P.

Gravitationally collapsing stars in f(R) gravity
European Physical Journal C: Particles and Fields, 2021 The gravitational dynamics of a collapsing matter configuration which is simultaneously radiating heat flux is studied in f(R) gravity. Three particular functional forms in f(R) gravity are considered to show that it is possible to envisage boundary ...

Stress–singularity analysis in space junctions of thin plates [PDF]
, 2000 The stress singularity in space junctions of thin linearly elastic isotropic plate elements with zero bending rigidities is investigated. The problem for an intersection of infinite wedge-shaped elements is considered first and the solution for each ...

Quantum dress for a naked singularity
Physics Letters B, 2016 We investigate semiclassical backreaction on a conical naked singularity space–time with a negative cosmological constant in (2+1)-dimensions. In particular, we calculate the renormalized quantum stress–energy tensor for a conformally coupled scalar ...

Equivariant singularity theory with distinguished parameters: Two case studies of resonant Hamiltonian systems [PDF]
, 1998 We consider Hamiltonian systems near equilibrium that can be (formally) reduced to one degree of freedom. Spatio-temporal symmetries play a key role. The planar reduction is studied by equivariant singularity theory with distinguished parameters.

Periodic solution for prescribed mean curvature Rayleigh equation with a singularity
Advances in Difference Equations, 2020 In this paper, we consider the existence of a periodic solution for a prescribed mean curvature Rayleigh equation with singularity (weak and strong singularities of attractive type or weak and strong singularities of repulsive type).
