Maximal -extensions of Pythagorean fields and Right Angled Artin Groups
Oussama Hamza, Christian Maire, Ján Mináč +1
In this paper, we describe minimal presentations of maximal pro- quotients of absolute Galois groups of formally real Pythagorean fields of finite type. For this purpose, we int…

On divisibility relation graphs
Jonathan L. Merzel, Ján Mináč, Tung T. Nguyen +1
For each positive integer , we define the divisibility relation graph whose vertex set is the set of divisors of , and in which two vertices are adjacent if one is a di…

Geometric perspective of linear stability in finite networks of nonlinear oscillators
Yashee Sinha, Priya B. Jain, Antonio Mihara +4
We use a complex-valued transformation of the Kuramoto model to develop an operator-description of the linear stability in finite networks of nonlinear oscillators. This mathematic…
