Hilbert transforms and the Cauchy integral in euclidean space [PDF]
, 2009 We generalize the notion of harmonic conjugate functions and Hilbert transforms to higher dimensional euclidean spaces, in the setting of differential forms and the Hodge-Dirac system.

Random-bond Ising model and its dual in hyperbolic spaces. [PDF]
Physical Review E, 2022 We analyze the thermodynamic properties of the random-bond Ising model (RBIM) on closed hyperbolic surfaces using Monte Carlo and high-temperature series expansion techniques.

General rotational ξ−surfaces in Euclidean spaces
, 2021 The general rotational surfaces in the Euclidean 4-space R was first studied by Moore (1919). The Vranceanu surfaces are the special examples of these kind of surfaces.

Low-dimensional de Sitter quantum gravity
Journal of High Energy Physics, 2020 We study aspects of Jackiw-Teitelboim (JT) quantum gravity in two-dimensional nearly de Sitter (dS) spacetime, as well as pure de Sitter quantum gravity in three dimensions.

Minimisers of a fractional seminorm and nonlocal minimal surfaces [PDF]
, 2020 The recent literature has intensively studied two classes of nonlocal variational problems, namely the ones related to the minimisation of energy functionals that act on functions in suitable Sobolev-Gagliardo spaces, and the ones related to the ...

On the Harmonic Evolute Surfaces of Hasimoto Surfaces
Adıyaman University Journal of Science, 2021 In this study, firstly by considering the evolution of a moving space curve, we give some related definitions and some new results about Hasimoto surfaces in Euclidean 3-spaces.

Triangulated Surfaces in Twistor Space: A Kinematical Set up for Open/Closed String Duality [PDF]
, 2006 We exploit the properties of the three-dimensional hyperbolic space to discuss a simplicial setting for open/closed string duality based on (random) Regge triangulations decorated with null twistorial fields.
