Investigation of the Roles of Dynamic Geometry Software in Problem Solving Skills and Conjecture Making [PDF]

Fanāvarī-i āmūzish, 2009
Teaching and learning geometry at secondary level have usually many problems. Researches indicate that use of Dynamic Geometry Software (DGS) can reduce some of these difficulties.

On AGT conjecture [PDF]

, 2009
In these notes we consider relation between conformal blocks and the Nekrasov partition function of certain $\mathcal{N}=2$ SYM theories proposed recently by Alday, Gaiotto and Tachikawa.

A FORMAL PROOF OF THE KEPLER CONJECTURE [PDF]

Forum of Mathematics, Pi, 2015
This article describes a formal proof of the Kepler conjecture on dense sphere packings in a combination of the HOL Light and Isabelle proof assistants. This paper constitutes the official published account of the now completed Flyspeck project.

Investigations on hoop conjecture for horizonless spherical charged stars

Nuclear Physics B, 2021
For horizonless spherical stars with uniform charge density, the hoop conjecture was tested based on the interior solution. In this work, we are interested in more general horizonless spherical charged stars.

THE BINARY GOLDBACH CONJECTURE

JOHME: Journal of Holistic Mathematics Education, 2021
The Goldbach Conjecture, one of the oldest problems in mathematics, has fascinated and inspired many mathematicians for ages. In 1742 German mathematician Christian Goldbach, in a letter addressed to Leonhard Euler, proposed a conjecture.

Further results on Hendry's Conjecture [PDF]

Discrete Mathematics & Theoretical Computer Science, 2022
Recently, a conjecture due to Hendry was disproved which stated that every Hamiltonian chordal graph is cycle extendible. Here we further explore the conjecture, showing that it fails to hold even when a number of extra conditions are imposed.

A global view of dynamics and a conjecture on the denseness of finitude of attractors

Astérisque, 2018
— A view on dissipative dynamics, i.e. flows, diffeomorphisms, and trans­ formations in general of a compact boundaryless manifold or the interval is presented here, including several recent results, open problems and conjectures.

Ontology of The Possible: on the Structure of the Object

Open Philosophy, 2018
This paper, through a realist reading of Husserlian phenomenology, aims to explain how the consciousness-sense has access to reality and, in general, to objectivity.

Evidence for a sublattice weak gravity conjecture [PDF]

, 2016
A bstractThe Weak Gravity Conjecture postulates the existence of superextremal charged particles, i.e. those with mass smaller than or equal to their charge in Planck units.

Spaces of Graphs, Boundary Groupoids and the Coarse Baum-Connes Conjecture

, 2013
We introduce a new variant of the coarse Baum-Connes conjecture designed to tackle coarsely disconnected metric spaces called the boundary coarse Baum-Connes conjecture.
