Characterizations of transcendental entire solutions of trinomial partial differential-difference equations in â„‚2#

open access: yesDemonstratio Mathematica
This study is devoted to exploring the existence and the precise form of finite-order transcendental entire solutions of second-order trinomial partial differential-difference equations L(f)2+2hL(f)f(z1+c1,z2+c2)+f(z1+c1,z2+c2)2=eg(z1,z2)L{(f)}^{2}+2hL(f)

Nevanlinna matrix estimates without regularity conditions [PDF]

open access: yesarXiv
The Nevanlinna matrix of a half-line Jacobi operator coincides, up to multiplication with a constant matrix, with the monodromy matrix of an associated canonical system. This canonical system is discrete in a certain sense, and is determined by two sequences, called "lengths" and "angles".
