An efficient algorithm for positive realizations
Wojciech Czaja, Philippe Jaming, Maté Matolcsi
We observe that successive applications of known results from the theory of positive systems lead to an {\it efficient general algorithm} for positive realizations of transfer func…
A geometric estimate on the norm of product of functionals
Mate Matolcsi
The open problem of determining the exact value of the -th linear polarization constant of has received considerable attention over the past few years. This paper m…
Fuglede's conjecture fails in dimension 4
Mate Matolcsi
In this note we give an example of a set $\W\subset \R^4$ such that $L^2(\W)$ admits an orthonormal basis of exponentials $\{\frac{1}{|\W |^{1/2}}e^{2πi x, ξ}\}_{ξ\inŁ}$ for some s…
Oscillation of Fourier transform and Markov-Bernstein inequalities
Szilard Gy. Revesz, Noli N. Reyes, Gino Angelo M. Velasco
Under certain conditions on an integrable function f having a real-valued Fourier transform Tf=F, we obtain a certain estimate for the oscillation of F in the interval [-C||f'||/||…
