S. N. Bernstein Type Estimations in the Mean on the Curves in a Complex Plane

open access: yesAbstract and Applied Analysis, 2009
The present paper discusses in the metric Lp S. N. Bernstein type inequalities of the most general kind on very general accessible classes of curves in a complex plane. The obtained estimations, generally speaking, are not improvable.

Jackson’s inequality in the complex plane and the Łojasiewicz–Siciak inequality of Green’s function

open access: yesJournal of Approximation Theory, 2016
We prove a generalization of Dunham Jackson's famous approximation inequality to the case of compact sets in the complex plane admitting both upper and lower bounds for their Green's functions, i.e. the well known Holder Continuity Property (HCP) and the less known but crucial Lojasiewicz-Siciak inequality (LS).

Extension of positivity bounds to non-local theories: IR obstructions to Lorentz invariant UV completions [PDF]

open access: yes, 2019
We derive positivity bounds on low energy effective field theories which admit gapped, analytic, unitary, Lorentz invariant, and possibly non-local UV completions, by considering 2 to 2 scatterings of Jaffe fields whose Lehmann-K\"{a}ll\'{e}n spectral ...

Nonlinear Inequalities and Entropy-Concurrence Plane [PDF]

open access: yes, 2006
Nonlinear inequalities based on the quadratic Renyi entropy for mixed two-qubit states are characterized on the Entropy-Concurrence plane. This class of inequalities is stronger than Clauser-Horne-Shimony-Holt (CHSH) inequalities and, in particular, are ...

Lipschitz conditions, triangular ratio metric, and quasiconformal maps

open access: yes, 2015
The triangular ratio metric is studied in subdomains of the complex plane and Euclidean $n$-space. Various inequalities are proven for it. The main results deal with the behavior of this metric under quasiconformal maps.
