Size Reduction of The Transfer Matrix of Two-Dimensional Ising and Potts Models
M. Ghaemi, G. A. Parsafar
A new algebraic method is developed to reduce the size of the transfer matrix of Ising and three-state Potts ferromagnets, on strips of width r sites of square and triangular latti…
Quantum error-correction codes on Abelian groups
Massoud Amini
We prove a general form of bit flip formula for the quantum Fourier transform on finite abelian groups and use it to encode some general CSS codes on these groups.
Tannaka-Krein duality for compact groupoids I, representation theory
Massoud Amini
In a series of papers, we have shown that from the representatio theory of a compact groupoid one can reconstruct the groupoid using the procedure similar to the Tannaka-Krein dual…
Restricted algebras on inverse semigroups I, representation theory
Massoud Amini, Alireza Medghalchi
The relation between representations and positive definite functions is a key concept in harmonic analysis on topological groups. Recently this relation has been studied on topolog…
Fourier Algebras On Topological Foundation *-Semigroups
Massoud Amini, Alireza Medghalchi
We introduce the notion of the Fourier and Fouier-Stieltjes algebra of a topological *-semigroup and show that these are commutative Banach algebras. For a class of foundation semi…
