A case of mu-synthesis as a quadratic semidefinite program

, 2013
We analyse a special case of the robust stabilization problem under structured uncertainty. We obtain a new criterion for the solvability of the spectral Nevanlinna-Pick problem, which is a special case of the $\mu$-synthesis problem of $H^\infty ...

Transient Offset in 14C After the Carrington Event Recorded by Polar Tree Rings

Geophysical Research Letters, Volume 51, Issue 5, 16 March 2024.
Abstract The Carrington event of 1859 has been the strongest solar flare in the observational history. It plays a crucial role in shedding light on the frequency and impacts of the past and future Solar Energetic Particle (SEP) events on human societies. We address the impact of the Carrington event by measuring tree‐ring 14C with multiple replications

Three-point Nevanlinna Pick problem in the polydisc

, 2015
It is very elementary to observe that functions interpolating an extremal two-point Pick problem on the polydisc are just left inverses to complex geodesics.

Properties of meromorphic solutions of $q$-difference equations

Electronic Journal of Differential Equations, 2015
In this article, we utilize Nevanlinna value distribution theory to study the solvability and the growth of meromorphic function f(z) that satisfies some q-difference equations, which can be seen the q-difference analogues of Painleve I and II ...

Collective and static properties of model two-component plasmas

, 2007
Classical MD data on the charge-charge dynamic structure factor of two-component plasmas (TCP) modeled in Phys. Rev. A 23, 2041 (1981) are analyzed using the sum rules and other exact relations.

The boundary Carath\'{e}odory-Fej\'{e}r interpolation problem [PDF]

, 2010
We give an elementary proof of a solvability criterion for the {\em boundary Carath\'{e}odory-Fej\'{e}r problem}: given a point $x \in \R$ and, a finite set of target values, to construct a function $f$ in the Pick class such that the first few ...

Value distribution and potential theory

, 2002
We describe some results of value distribution theory of holomorphic curves and quasiregular maps, which are obtained using potential theory. Among the results discussed are: extensions of Picard's theorems to quasiregular maps between Riemannian ...
