\section{Abstract}
|
||||
|
||||
Complex Analysis is a very active branch of mathematics with applications in many other fields.
|
||||
The proposed workshop presents recent results in complex
|
||||
analysis and surveys progress in topics that link the field to other branches of mathematics.
|
||||
%This application highlights differential-geometric methods in the study of singular spaces, the interplay between analytic and algebraic methods, and the relation between complex analysis and Scholze-Clausen's condensed mathematics.
|
||||
The proposed workshop will present recent advances in the analytic and algebraic
|
||||
study of Kähler spaces. Key topics to be covered include:
|
||||
\begin{itemize}
|
||||
\item Canonical metrics and their limits,
|
||||
|
||||
%The meeting has always been a venue where confirmed researchers from different backgrounds meet and where young mathematicians are giving their first talks at an international conference. While we are happy to see a growing number of talented, young researchers, we feel that this age group suffers the most from the ongoing COVID crisis and the resulting lack of exchange and interaction. We would therefore like to emphasize the contributions of younger researchers and invite a relatively higher number of them. We are looking forward to welcoming them to Oberwolfach, rediscover the pleasure of meeting in person, and exchange points of view!
|
||||
\item Hyperbolicity properties of complex algebraic varieties,
|
||||
|
||||
\item The topology and Hodge theory of Kähler spaces.
|
||||
\end{itemize}
|
||||
While these topics are classical, various breakthroughs were achieved only
|
||||
recently. Moreover, each is closely linked to various other branches of
|
||||
mathematics. For example, geometric group theorists have recently applied
|
||||
methods from complex geometry and Hodge theory to address long-standing open
|
||||
problems in geometric group theory. Similarly, concepts used in the framework
|
||||
of hyperbolicity questions, such as entire curves, jet differentials and
|
||||
Nevanlinna theory have recently seen important applications in the study of
|
||||
rational and integral points in number theory. To foster further
|
||||
interdisciplinary collaboration, we will invite several experts from related
|
||||
fields to participate in the workshop.
|
||||
|
||||
The workshop has a distinguished history, originating with Grauert and Remmert.
|
||||
The 2026 edition brings in new organizers with fresh perspectives. About half
|
||||
of the proposed participants have not attended this workshop before. To ensure a
|
||||
smooth transition, we decided to retain two of the established organizers for
|
||||
this application; we plan to replace both of them in the next application for
|
||||
2029.

\section{Description of the Workshop}
|
||||
|
||||
The proposed workshop presents recent results in Complex Geometry and surveys

||||
relations to other fields. For 2026, we would like to emphasize the fields
|
||||
described below.
|
||||
Each relates to complex analysis differently.
|
||||
Each has seen substantial progress recently, producing results that will be of importance for years to come.
|
||||
%The bullet items list some of the latest developments that have attracted our attention.
|
||||
|
||||
%We plan to include at least one broader overview talk for each of the three subjects, as well as more specialized presentations by senior experts and junior researchers.
|
||||
We will account for new developments that arise between the time of submission
|
||||
of this proposal and the time of the workshop. Following good Oberwolfach
|
||||
tradition, we will keep the number of talks small to provide ample opportunity
|
||||
for informal discussions.
|
||||
%After so many months of the pandemic, this will be more than welcome!
|
||||
The proposed workshop presents recent results in Complex Geometry and Kähler
|
||||
spaces, focusing on a combination of analytic and algebraic methods. We aim to
|
||||
emphasize the fields described below, each rooted in complex analysis and
|
||||
interconnected with various other branches of mathematics.
|
||||
|
||||
An important goal of our workshop is to foster collaborations between
|
||||
mathematicians from different communities, with diverse backgrounds and
|
||||
perspectives. We have invited experts from related fields, and we will ask them
|
||||
to give survey talks on their work early in the week. This will allow them to
|
||||
introduce themselves to the complex geometers attending the workshop and provide
|
||||
ample opportunities for discussions throughout the rest of the week. Following
|
||||
the Oberwolfach guidelines, we will keep the number of talks comparatively small
|
||||
(no more than 25) to allow for plenty of informal discussions.
|
||||
|
||||
One evening during the workshop, we will hold a special session where junior
|
||||
participants who are not selected to give a 60-minute talk can give a 5-10
|
||||
minute pitch on their work to introduce themselves to the community.

Ever since its invention, Hodge theory has been one of the most powerful tools

in studying the geometry and topology of Kähler spaces. More recent

developments connect the theory to singularity theory, commutative algebra, and

the topology of algebraic varieties. The following topics in this area will

if their tenure is less than about three years old.}. About half of them have
