This is the start of homology! We're embedding elementary manifolds (lines, triangles, tetrahedra, etc.) and looking at their boundaries! Specifically at how their boundaries "cancel" or don't If I were your teacher, I would now guide you through a series of examples where
How do you prove that the circle and the line are not homeomorphic? Well, if you work really hard you can show that one is contractible and the other is not (exercise) But like: just look at them! They're obviously different! The circle has a "hole" while the line doesn't
せっかくだから、Mathematicaでpersistent homologyを勉強する。 persistent homologyについては Introduction to Persistent Homology for Graph Analysis (PDF)が分かりやすい www2.math.kyushu-u.ac.jp/~skaji/slides/…
Homotopy invariance ensures properties remain constant under continuous deformation (stretching or bending). In machine learning, this powers Topological Data Analysis (TDA), allowing models to extract robust features from noisy data—recognizing that a distorted handwritten digit…
The graph of 𝘧 in ℝ³ is a connected 2d-surface homeomorphic to ℝ². The roots of 𝘧 are points of the surface touching the 0-plane. One can nudge the areas around the roots up or down to separate this connected surface into +& - pieces … v —— (intuitive approach) ^

Give your class this chart. Then maybe your teacher will make time to teach you something valuable.
A graph is nonplanar if and only if it contains a subgraph that is homeomorphic to K5 or K3,3
Does anyone have any random fun facts about a very niche subject. I'm bored and love learning random things
Homology is a fundamental concept in algebraic topology. It allows you to quantify how many holes a space has. When I first learned it, however, it was very mystifying. It took me years to understand the intuitions behind it. In this thread, I wanted to share this intuition at…
A topological space of fonts 🔤 Do you see the separation of serif and non-serif fonts? bit.ly/3dDMb67 (Neill D.F. Campbell and Jan Kautz, SIGGRAPH 2014) #math #science #iteachmath #mtbos #visualization #elearning #topology
this has become my most used reference in the notes for my 3D editor it's a diagram with names of all topology traversal functions I've got - all relative to the black half edge with a white outline in the middle
More formally, each point has a neighbourhood that is homeomorphic to Euclidean space. For example, the Earth appears to be locally flat, but is in fact round!
Natural graphs don't look like hairballs if you stratify them by node degree during layout. They look like beautiful mountains 🏔️😍 Here is an ego graph, where each node is bound to Z=deg(node) plane
