<h5 id="february-13-16-2023">February 13-16, 2023</h5>
<p>The workshop aims at bringing together experts from Mathematics and
Physics to discuss the latest developments and future directions in
unraveling the Mathematical Structures in Feynman Integrals. Topics
will include among others Structures of Feynman integrals, Integral
reduction, Applications from algebraic geometry, Finite fields and
rational reconstruction, Differential equations, etc.</p>
<p>The program will feature dedicated talks, but will also leave ample
time for discussions among workshop participants.</p>
<p>February 11, 2023 marks the 100th anniversary of the death of the
mathematician Wilhelm Killing, born in Burbach, only 20km from
Siegen. Killing formulated a research program that is still relevant
today and has significantly influenced mathematical research for a
century. The 100th anniversary of Killing’s death is an appropriate
opportunity to honour his merits with an inaugural talk by

<h6 id="abstract">Abstract:</h6>
<p>Chevalley proved that the image of an algebraic morphism between
algebraic varieties is a constructible set. Examples are orbits of
algebraic group actions. A constructible set in a topological space is
a finite union of locally closed sets and a locally closed set is the
difference of two closed subsets. Simple examples show that even if
the source and target of the morphism are affine varieties the image
may neither be affine nor quasi-affine. In this talk, I will present a
Gröbner-basis-based algorithm that computes the constructible image of
a morphism of affine spaces, along with some applications.</p>

of Quantum Information”, to take place in March 2019 in Siegen
(Germany).</p>
<p>The idea of the workshop is the following: The connection between
quantum physics and information theory has posed new challenges at the
border between mathematics and physics. The workshop will bring
together experts from physics (entanglement theory, information
theory, many- body physics) with mathematicians (optimization,
multilinear algebra, Gröbner bases) in an informal manner. This should
allow many discussions and the mutual exchange of ideas.</p>
<p>The workshop will take place in Siegen (Germany) from March 18-21,</p>

<p><a href="http://homalg-project.github.io/CAP_project/">CAP (Categories, Algorithms, Programming)</a> is a software project for constructive category theory written in GAP. It facilitates both the realization of specific instances of categories and the implementation of generic categorical algorithms.</p>
<p>The workshop aims at mathematicians who want to learn about the CAP project, categorical programming, and structurizing implementations in a categorical way. The workshop is suitable for both GAP newcomers and veteran GAP programmers.</p>
<p>The workshop is split in three parts:</p>
<p>Talks
Tutorial
