Sylvester Hadamard matrices revisited

open access: yesSpecial Matrices, 2014
In this work we revisited some properties of Sylvester Hadamard matrices of order 2k. Based onlyon the existence of a base from which any Sylvester Hadamard matrix can be constructed, we prove that theirrows (columns) are closed under addition and that ...

M-matrices satisfy Newton's inequalities

open access: yes, 2005
Newton's inequalities $c_n^2 \ge c_{n-1}c_{n+1}$ are shown to hold for the normalized coefficients $c_n$ of the characteristic polynomial of any $M$- or inverse $M$-matrix.

On the exact decryption range for Gentry–Halevi's implementation of fully homomorphic encryption

open access: yesJournal of Mathematical Cryptology, 2014
In this paper, we revisit the fully homomorphic encryption (FHE) scheme implemented by Gentry and Halevi, which is just an instantiation of Gentry's original scheme based on ideal lattices.

ON A POWER OF THE COMPANION MATRIX

open access: yesSüleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2009
: In this study, we have given some results which have computed power of the companion matrix and the algorithms which are based on these results. So we also have given numerical examples using these algorithms.
