SINR Diagrams: Towards Algorithmically Usable SINR Models of Wireless Networks
Chen Avin, Yuval Emek, Erez Kantor +3
The rules governing the availability and quality of connections in a wireless network are described by physical models such as the signal-to-interference & noise ratio (SINR) model…
On The Structure and Automorphism Group of Finite Alexander Quandles
Amiel Ferman, Tahl Nowik, Mina Teicher
We prove that an Alexander quandle of prime order is generated by any pair of distinct elements. Furthermore, we prove for such a quandle that any ordered pair of distinct elements…
The quiver of an algebra associated to the Mantaci-Reutenauer descent algebra and the homology of regular semigroups
Stuart Margolis, Benjamin Steinberg
We develop the homology theory of the algebra of a regular semigroup, which is a particularly nice case of a quasi-hereditary algebra in good characteristic. Directedness is charac…
Stirring Astronomy into Theology: Sir Isaac Newton on the Date of the Passion of Christ
Ari Belenkiy, Eduardo Vila Echague
It is known that Sir Isaac Newton suggested a date for the Passion of Christ in the posthumously published "Observations upon the Prophecies of Daniel and the Apocalypse of St. Joh…
On the Cayley semigroup of a finite aperiodic semigroup
Avi Mintz
Let be a finite semigroup. In this paper we introduce the functions , first defined by Rhodes, given by $ϕ_s([a_1,a_2 ,...,a_n]) = [sa_1,sa_1a_2,..., sa_1a_2 .…
Multifactor Analysis of Multiscaling in Volatility Return Intervals
Fengzhong Wang, Kazuko Yamasaki, Shlomo Havlin +1
We study the volatility time series of 1137 most traded stocks in the US stock markets for the two-year period 2001-02 and analyze their return intervals , which are time interv…
