On multivariate Newton-like inequalities
Leonid Gurvits
We study multivariate entire functions and polynomials with non-negative coefficients. A class of {\bf Strongly Log-Concave} entire functions, generalizing {\it Minkowski} volume p…
The Apparent "Angular Size - Frequency" Dependence in ~3000 Parsec-scale Extragalactic Jets
J. Yang, L. I. Gurvits, S. Frey +1
The upper envelope of the amplitude of the VLBI visibility function usually represents the most compact structural pattern of extragalactic radio sources, in particular, the "core-…
High-resolution double morphology of the most distant known radio quasar at z=6.12
S. Frey, L. I. Gurvits, Z. Paragi +1
Context: The highest redshift quasars at z>~6 receive considerable attention since they provide strong constraints on the growth of the earliest supermassive black holes. They also…
A short, based on the mixed volume, proof of Liggett's theorem on the convolution of ultra-logconcave sequences
Leonid Gurvits
R. Pemantle conjectured, and T.M. Liggett proved in 1997, that the convolution of two ultra-logconcave is ultra-logconcave. Liggett's proof is elementary but long. We present here…
High-Redshift Quasars at the Highest Resolution: VSOP Results
S. Frey, L. I. Gurvits, A. P. Lobanov +2
We studied the radio structure of high-redshift (z>3) quasars with VSOP at 1.6 and 5 GHz. These sources are the most distant objects ever observed with Space VLBI, at rest-frame fr…
