Lih Wang's and Dittert's conjectures on permanents

open access: yesSpecial Matrices
Let Ωn{\Omega }_{n} denote the set of all doubly stochastic matrices of order nn. Lih and Wang conjectured that for n≥3n\ge 3, per(tJn+(1−t)A)≤t\left(t{J}_{n}+\left(1-t)A)\le tperJn+(1−t){J}_{n}+\left(1-t)perAA, for all A∈ΩnA\in {\Omega }_{n} and all t ...

On the spectrum of tridiagonal matrices with two-periodic main diagonal

open access: yesSpecial Matrices
We find the spectrum and eigenvectors of an arbitrary irreducible complex tridiagonal matrix with two-periodic main diagonal. This is expressed in terms of the spectrum and eigenvectors of the matrix with the same sub- and superdiagonals and zero main ...

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.

HART EFFECT AND EQUILIBRIUM IN INCOMPLETE MARKETS I [PDF]

open access: yes
In this paper I reconsider the problem of the existence for GEI models. It is well known that existence for this kind of models can fail since there are bad spot prices.
