PhD Colloquia

December 9, 2024 – TUForMath Room, TU Wien (Freihaus)
3.30 pm: Fabian Zehetgruber (TU Wien) – Iterative Construction of Neural Networks
Abstract: In typical neural network design, we define an architecture and train it on a dataset. In this talk, we will explore a different approach: constructing
neural networks iteratively through a process of composition and addition. By progressively combining simpler networks, we can approximate certain functions very efficiently.
This method relies on the combination of neural network operations — such as addition and composition — and is supported by the Banach Fixed Point Theorem, which provides a mathematical basis for proving convergence of the iterative process. In the talk, we will see simple examples of function approximation using this iterative approach. Please find the poster here.

4.00 pm: PhD Colloquium – Matthias Ostermann: Stable Blowup for Semilinear Wave Equations
Nonlinear wave equations exhibit a wide variety of fascinating dynamics. Among them is the formation of singularities in finite time from smooth initial data. This is illustrated e.g. for wave equations with focusing power nonlinearities by an explicit solution, the so-called ODE blowup, in all space dimensions. Whether this blowup mechanism plays a universal role in the generic wave evolution leads to the central question about its stability. This talk gives an elementary introduction to the ideas and methods behind a recently developed stability theory for blowup in wave equations with application to the ODE blowup.

2.00 pm: PhD Colloqium – Eric Stenhede: How to build 3-manifolds
A manifold is a topological space that is Hausdorff, second countable, and locally homeomorphic to Euclidean space. While it is relatively easy to visualize 0-, 1-, and 2-dimensional manifolds, it becomes more challenging to picture the higher-dimensional ones. In the case of dimension 3, we can only imagine the local model, the 3-dimensional Euclidean space. However, by adopting certain conventions, we can go beyond that and develop a certain feeling for what 3-manifolds look like.
In this talk, I will discuss and survey various methods for constructing and visualizing 3-dimensional manifolds: triangulations, Heegaard splittings, and surgery diagrams. The goal is to sketch the proof of the Lickorish-Wallace theorem.
If time permits, I will also discuss the relationship between 3-dimensional and 4-dimensional topology through handle decompositions.

2.00 pm: PhD Colloqium – Eric Stenhede: How to build 3-manifolds
A manifold is a topological space that is Hausdorff, second countable, and locally homeomorphic to Euclidean space. While it is relatively easy to visualize 0-, 1-, and 2-dimensional manifolds, it becomes more challenging to picture the higher-dimensional ones. In the case of dimension 3, we can only imagine the local model, the 3-dimensional Euclidean space. However, by adopting certain conventions, we can go beyond that and develop a certain feeling for what 3-manifolds look like.
In this talk, I will discuss and survey various methods for constructing and visualizing 3-dimensional manifolds: triangulations, Heegaard splittings, and surgery diagrams. The goal is to sketch the proof of the Lickorish-Wallace theorem.
If time permits, I will also discuss the relationship between 3-dimensional and 4-dimensional topology through handle decompositions.
Please find the poster here.
