On the phase space of free higher-spin theories and conformal transformations

open access: yesNuclear Physics B, 2017
We write a first order action for higher-spin fields and construct a canonical map to Fronsdal theory. The first-order description is defined over complex field configurations and has conformal invariance.

Crossing-symmetric twist field correlators and entanglement negativity in minimal CFTs

open access: yesJournal of High Energy Physics, 2021
We study conformal twist field four-point functions on a ℤ N orbifold. We examine in detail the case N = 3 and analyze theories obtained by replicated N-times a minimal model with central charge c < 1.

Conformal Mapping in Linear Time [PDF]

open access: yesDiscrete & Computational Geometry, 2010
Given any $ε>0$ and any planar region $Ω$ bounded by a simple n-gon $P$ we construct a ($1 + ε)$-quasiconformal map between $Ω$ and the unit disk in time $C(ε)n$. One can take $ C(ε) = C + C \log (1/ε) \log \log (1/ε)$.

On Riemannian manifolds endowed with a locally conformal cosymplectic structure

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
We deal with a locally conformal cosymplectic manifold M(φ,Ω,ξ,η,g) admitting a conformal contact quasi-torse-forming vector field T. The presymplectic 2-form Ω is a locally conformal cosymplectic 2-form.

Boundary conformal anomalies on hyperbolic spaces and Euclidean balls

open access: yesJournal of High Energy Physics, 2017
We compute conformal anomalies for conformal field theories with free conformal scalars and massless spin 1/2 fields in hyperbolic space ℍ d and in the ball Bd $$ {\mathbb{B}}^d $$, for 2≤d≤7. These spaces are related by a conformal transformation.

How round is a protein? Exploring protein structures for globularity using conformal mapping.

open access: yesFrontiers in Molecular Biosciences, 2014
We present a new algorithm that automatically computes a measure of the geometric difference between the surface of a protein and a round sphere. The algorithm takes as input two triangulated genus zero surfaces representing the protein and the round ...

Rigidity Characterizations of Conformal Solitons

open access: yesMathematics
We study the rigidity of conformal solitons, give a sufficient and necessary condition that guarantees that every closed conformal soliton is gradient conformal soliton, and prove that complete conformal solitons with a nonpositive Ricci curvature must ...

Remarks on conformal anti-invariant Riemannian maps to cosymplectic manifolds

open access: yes, 2021
M. A. Akyol and B. \c{S}ahin [Conformal anti-invariant Riemannian maps to Kaehler manifolds, U.P.B. Sci. Bull., Series A, Vol. 80, Iss. 4, 2018] defined and studied the notion of conformal anti-invariant Riemannian maps to Kaehler manifolds.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
