Undergraduate research topics in topology?

AI Thread Summary
The discussion centers on finding a suitable topic for an undergraduate dissertation in Mathematics and Computing, particularly focusing on advanced mathematical concepts. The student has a solid foundation in multivariable calculus, differential geometry, and some knowledge of topology and algebraic topology. Suggested dissertation topics include exploring the Banach-Tarski paradox and its implications regarding the axiom of choice, analyzing a specific analytical group and its differential geometry properties, and investigating algebraic topology aspects such as homology groups. Other recommendations involve discussing fractal dimensions, examining the topology of p-adic numbers, and delving into differential topology topics, including Milnor's work and deRham cohomology. The importance of consulting with an academic advisor for tailored guidance on topic viability and complexity is also emphasized.

TL;DR Summary: In search of a suitable topic for an interesting undergraduate dissertation.

I am a final year Mathematics and Computing undergraduate. I am expected to submit an extensive B.Sc. thesis in four months. I have previously studied multivariable calculus, differential fields and forms, integration on chains, and a little bit of Theory of manifolds (mainly building to Stokes' theorem following the pathway in Calculus on Manifolds, Michael Spivak). I am comfortable with concepts in point set topology and have a limited knowledge in Algebraic Topology (Topology by James Munkres) (having finished courses on abstract algebraic structures beforehand), and plan to expand it within the next 3-4 weeks. I am in search of a topic suitable for an interesting undergraduate dissertation culminating the above mentioned subjects. Thanks to anyone who takes the time to read and write me some input.

Hello again!

I have a few ideas but I don't know whether they fit your profile.

1) Elaborate the proof and discuss what is the crucial point of the Banach-Tarski paradox, in particular concerning the question of whether it is the axiom of choice or our lack of understanding the concept of points that makes it so surprising.

2) ##G=\left\{\left.\begin{pmatrix}e^t&0\\0&e^{-t}\end{pmatrix}\, , \,\begin{pmatrix}1&x\\0&1\end{pmatrix}\right| \;t,x\in \mathbb{R}\right\}## defines an analytical (topological) group (manifold). Elaborate the various terms of differential geometry like atlas, geodesics, Levi-Civita connection, etc. on this example.

3) You could use the same example for algebraic topology and calculate its properties: compact or not, (path-) connected or not, homology groups, (co-)chain complexes, its Lie algebra, and the Cartan-Eilenberg complex.

4) Or you could discuss the various definitions of dimensions of fractals.

If you want to have something new, I can only hand you an algebraic topic.

OP: Any suggestions from your advisor, who should best know the level expected and what is viable within the allotted time?

You list a broad range of subjects that the topic can "culminate in" but the title specifies topology. Are you restricting your request to topology?

If you want to do something on topological fields, you could

5) investigate the topology on p-adic numbers and their approximation theorem.
or
6) function theory on p-adic numbers,
or
7) any other (or all) approximation theorems.

p-adic numbers

I stumbled upon this Veritasium video, which is about p-adic numbers. I'm not a mathematician by any means but this really blew my mind. Fascinating.

Something Strange Happens When You Keep Squaring
 
Late to the discussion, but with your background, a topic in differential topology seems appropriate, such as expositing some of Milnor's Topology from the differentiable viewpoint, maybe even the final Hopf theorem on framed cobordism, or part of chapter 1 of Bott-Tu, covering deRham cohomology, Mayer Vietoris, and Poincare duality.
