HOLOMORPHIC EXTENSIONS AND DECAY ON INFINITY FOR CLASSES OF PDEs IN $\R^n$
Abstract. The aim of the talk is twofolded. First, we
give an overview of recent results on the uniform
analytic-Gevrey regularity
%$G^\mu$, $0< \nu < 1$,
and the decay for $|x| \rightarrow \infty$ of solutions to
(semi--)linear elliptic differential equations in $\R^n$ in the
frame of the Gelfand--Shilov spaces $S^\mu_\nu (\R^n)$.
In the second part we present some new theorems for classes of
degenerate linear partial differentail operators in tensorized
generalizations of Shubin spaces and in inductive and projective
Gelfand--Shilov spaces $S^\mu_\mu (\R^n)$ for $\mu \geq 1/2$. In
particular, if $\mu \in [1/2, 1[$, we derive extensions of
solutions to entire fuctions of exponential type even if the
operators are not elliptic. We also outline abstract
functional--analytic generalizations.
These results are obtained in collaboration with Stevan Pilipovi\'
c (University of Novi Sad) and Luigi Rodino (Universit\`a di
Torino).
Predavanja ce se odrzavati na Matematickom Institutu (sala 2), petkom sa pocetkom u 14 casova. Odeljenje za matematiku je opsti seminar sa najduzom tradicijom u Institutu.
Svakog meseca, jedno predavanje ce biti odrzano na Matematickom Fakultetu u terminu koji ce biti posebno odredjen.
Molimo sve zainteresovane ucesnike u radu naucnih sastanaka da posebno obrate paznju na vreme odrzavanja svakog sastanka. Na Matematickom fakultetu su moguce izmene termina.
Obavestenje o programu naucnih sastanaka ce biti objavljeno na oglasnim tablama MI (Beograd), MF (Beograd), PMF (Novi Sad), PMF (Nis) i PMF (Kragujevac).
