Applications of Topology to real life problems.
I studied topology for 2 semesters.It's fun but the biggest problem i had is to prove theorems and lemmas on my own.
I do understand partially When my professor teaches me but very difficult for me to prove his assignments and homework.
Infact on a scale of 10, I am able to prove 2 ; Which is very bad.How can i ameliorate this situation ?
I also want to have ideas of the applications of Topology to real life problems.

Re: Applications of Topology to real life problems.
This may help. In addition to the things mentioned in the link, applications of Topology to Physics.
A comment from there:
A comment from there:
Of course, "real life" problems is a very ambiguous term. Some people may consider proving Tychonoff's theorem to be a real life problem.Topology is useful to mathematics as a whole. Mathematics is useful to humanity. By transitivity, Topology is useful to humanity.

More specific examples:
1. This paper uses Topology to analyze complex networks. E.g. social networks, biological networks, internet etc.
http://arxiv.org/pdf/1204.6376.pdf
2. This paper applies Differential Topology to probability to identify multivariate interactions. This was used in neuroscience recently to deduce how neurons are interacting.

Re: Applications of Topology to real life problems.
Brouwer's fixed point theorem can be used to conclude that if you swirl around your coffee in your coffee mug, then after you're done swirling, there is one drop of coffee that ended up back where it was before you moved anything around. This is the kinda shit that trips me out
Re: Applications of Topology to real life problems.
I have heard the one that says if you take a map of any size and drop it on the area it represents, there is a point on the map that is touching exactly the point it represents on the area. Fuzzy memory but might need the Intermediate Value Theorem for this.CoxZucker_Machine wrote:Brouwer's fixed point theorem can be used to conclude that if you swirl around your coffee in your coffee mug, then after you're done swirling, there is one drop of coffee that ended up back where it was before you moved anything around.

But the coffee fact is fuuuuuuun!!!
Re: Applications of Topology to real life problems.
It's the same thing Indeed, Brouwer Fixed Point theorem is a simple corollary of Intermediate Value Theorem in the R > R case.

There is also this:

That paper discusses using cell phones to actually map out the topology of indoor spaces. I also know one can use topology maps for automated robot navigation. Lots of machine learning applications as well. Another cool application is in the world of chemistry where one can discuss the shape of molecules by an analysis of the topology of a related graph. There is also an application for medical imaging software and technology. I'm pretty sure one can find an example of the application of topology to basically every field of the sciences.
Applied topology has become a pretty hot area of research recently. I know Math Fest in Madison 2012 had some great talks on applied topology, so I imagine there will be other conferences centered around this topic in the future. Maybe try to go to one. Here's a list of conferences that will have such topics.

Oh wow this topic is getting interesting. Never thought "Applied Topology" would be a branch!

I am suddenly looking forward to my Topology coursework.

@Legendre Thanks for the nice link!
