Neural Network Prediction of solar cycle 24
A. Ajabshirizadeh, N. Masoumzadeh Jouzdani, S. Abbassi
The ability to predict the future behavior of solar activity has become of extreme importance due to its effect on the near Earth environment. Predictions of both the amplitude and…
On the Automorphisms and Representations of Polyadic Groups
Hamid Khodabandeh, Mohammad Shahryari
Using a unified method, we determine the structure of automorphisms and representations of arbitrary polyadic groups. More precisely, for a polyadic group $(G, f)=der_{θ, b}(G, \cd…
A Note on Derivations of Lie Algebras
Mohammad Shahryari
In this note, we will prove that a finite dimensional Lie algebra of characteristic zero, admitting an abelian algebra of derivations with the property $$ L^n\su…
Constructing Entanglement Witness Via Real Skew-Symmetric Operators
M. A. Jafarizadeh, N. Behzadi
In this work, new types of EWs are introduced. They are constructed by using real skew-symmetric operators defined on a single party subsystem of a bipartite dxd system and a maxim…
Entanglement Witnesses and Characterizing Entanglement Properties of Some PPT States
M. A. Jafarizadeh, N. Behzadi, Y. Akbari
On the basis of linear programming, new sets of entanglement witnesses (EWs) for 3x3 and 4x4 systems are constructed. In both cases, the constructed EWs correspond to the hyperplan…
Separating Bounded Arithmetics by Herbrand Consistency
Saeed Salehi
The problem of separating the hierarchy of bounded arithmetic has been studied in the paper. It is shown that the notion of Herbrand Consistency, in its full generality, cann…
