On the Teichm{ü}ller space of acute triangles
Hideki Miyachi, Ken'Ichi Ohshika, Athanase Papadopoulos
We continue the study of the analogue of Thurston's metric on the Teichm{ü}ller space of Euclidean triangle which was started by Saglam and Papadopoulos in [1].By direct calculatio…
Timelike Hilbert geometry of the spherical simplex
Athanase Papadopoulos, Sumio Yamada
We prove the following result on the timelike spherical Hilbert geometry of simplices: Let be a simplex on the 2-sphere and the antipodal simplex. We show that th…
Some notes on the impact of Lagrange's memoir "On the construction of geographical maps"
Athanase Papadopoulos
These are notes on the impact of Lagrange's memoir on the construction of geographical maps. We mention the relations of some ideas and questions introduced in this memoir with oth…
The Teichm{ü}ller-Randers metric
Hideki Miyachi, Ken'Ichi Ohshika, Athanase Papadopoulos
In this paper, we introduce a new asymmetric weak metric on the Teichm{ü}ller space of a closed orientable surface with (possibly empty) punctures.This new metric, which we call th…
On Delisle's geographical projection
Charalampos Charitos, Athanase Papadopoulos
Joseph-Nicolas Delisle was one of the most important scientists at the Saint Petersburg Academy of Sciences during the first period when Euler was working there. Euler was helping…
Clairaut, Euler and the figure of the Earth
Athanase Papadopoulos
The sphericity of the form of the Earth was questioned around the year 1687, primarily, by Isaac Newton who deduced from his theory of universal gravitation that the Earth has the…
