\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
particularly interest our workshop.

Hwang's result in \cite{arXiv:2311.08977}. Hopefully, these methods will give

Below is a preliminary list of 55 people (including organizers) we would like to
invite\footnote{We list colleagues as ``young'' if they have no tenured job, or
if their tenure is less than about three years old.}. About half of them have
not attended this workshop before. The list meets or exceeds the quota on
diversity and regionality laid out in the ``Proposal Guidelines for Workshops''.
