High-resolution radio imaging of the most distant radio quasar SDSS J0836+0054
S. Frey, Z. Paragi, L. Mosoni +1
We observed SDSS J0836+0054, the most distant radio-loud quasar known at present (z=5.774) with the European Very Long Baseline Interferometry (VLBI) Network at the 5 GHz frequency…
A proof of hyperbolic van der Waerden conjecture : the right generalization is the ultimate simplification
Leonid Gurvits
Consider a homogeneous polynomial of degree in complex variables . Assume that this polynomial satisfies the property : \\ $|p(z_1,...,z_n)| \geq \prod_{1…
The highest redshift radio quasar as seen with the EVN and the VLA
S. Frey, Z. Paragi, L. Mosoni +1
We report on European VLBI Network (EVN) and Very Large Array (VLA) observations of SDSS J0836+0054, the most distant radio-loud quasar known at present z=5.774). The source, with…
Van der Waerden Conjecture for Mixed Discriminants
Leonid Gurvits
We prove that the mixed discriminant of doubly stochastic -tuples of semidefinite hermitian matrices is bounded below by and that this bound is u…
On Matrix Polynomials with Real Roots
Leonid Gurvits, Leiba Rodman
It is proved that the roots of combinations of matrix polynomials with real roots can be recast as eigenvalues of combinations of real symmetric matrices, under certain hypotheses.…
