Focusing of geodesic congruences in an accelerated expanding Universe [PDF]
, 2012 We study the accelerated expansion of the Universe through its consequences on a congruence of geodesics. We make use of the Raychaudhuri equation which describes the evolution of the expansion rate for a congruence of timelike or null geodesics.

Sequences of Enumerative Geometry: Congruences and Asymptotics [PDF]
Experimental Mathematics, 2008 We study the integer sequence υn of numbers of lines in hypersurfaces of degree 2 n − 3 of ℙ n , n > 1. We prove a number of congruence properties of these numbers of several different types. Furthermore, the asymptotics of the υ n are described (in an appendix by Don Zagier).

Geometric correlation of cultural landscape patterns and Prunus domestica L. species leaf [PDF]
Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2011 This paper provides the basics for more detailed research on the structures of bionic forms of different plant species and their application in the domain of landscape planning.

Breaking the Conformal Gauge by Fixing Time Protocols [PDF]
, 2014 We review the definition by Perlick of standard clocks in a Weyl geometry and show how a congruence of clocks can be used to fix the conformal gauge in the EPS framework.

Modular curves and the refined distance conjecture
Journal of High Energy Physics, 2021 We test the refined distance conjecture in the vector multiplet moduli space of 4D N $$ \mathcal{N} $$ = 2 compactifications of the type IIA string that admit a dual heterotic description.

Stringlike structures in Kerr-Schild geometry: N=2 string, twistors and Calabi-Yau twofold [PDF]
, 2013 Four-dimensional Kerr-Schild geometry contains two stringy structures. The first one is the closed string formed by the Kerr singular ring, and the second one is an open complex string with was obtained in the complex structure of the Kerr-Schild ...
