The Co-evolution of Cooperation and Epidemic Spreading
Mehran Noori, Nahid Azimi-Tafreshi, Mohammad Salahshour
People's cooperation in adopting protective measures is effective in epidemic control and creates herd immunity as a public good. Similarly, the presence of an epidemic is a drivin…
Construction of All Gyrogroups of Orders at most 31
Ali Reza Ashrafi, Kurosh Mavaddat Nezhaad, Mohammad Ali Salahshour
The gyrogroup is the closest algebraic structure to the group ever discovered. It has a binary operation containing an identity element such that each element has an invers…
Counting Centralizers of a Finite Group with an Application in Constructing the Commuting Conjugacy Class Graph
A. R. Ashrafi, M. A. Salahshour
The set of all centralizers of elements in a finite group is denoted by and is called centralizer if . In this paper, the structure of centrali…
Collective Movement with Signaling
Mohammad Salahshour, Shahin Rouhani
We consider a population of mobile agents able to make noisy observation of the environment and communicate their observation by production and comprehension of signals. Individual…
Construction of New Gyrogroups and the Structure of their Subgyrogroups
S. Mahdavi, A. R. Ashrafi, M. A. Salahshour
Suppose that is a groupoid with binary operation . The pair is said to be a gyrogroup if the operation has a left identity, each element $a \in…
Evolutionary value of collective sensing
Mohammad Salahshour, Shahin Rouhani
We propose a mathematical model for collective sensing in a population growing in a stochastically varying environment. In the population, individuals use an information channel fo…
