About – ErdosNinth
https://erdosninth.wordpress.com/about
List of blog posts. A blog about math. As Paul Erdos once said,. 8220;Why are numbers beautiful? It’s like asking why is Beethoven’s Ninth Symphony. Beautiful. If you don’t see why, someone can’t tell you. I know. Numbers are beautiful. If they aren’t beautiful, nothing is.”. It is from this quote that we draw our inspiration, as we truly wish to share the beauty and elegance of mathematics. It should be noted that the topics will most likely not be ordered for one to learn. Their existing knowledge....

List of blog posts. A blog about math. Written by Sanath Devalapurkar. December 14, 2016. December 14, 2016. FP on simplicial groups. It’s a good exercise to create fun problems (FPs). Here’s one: Show that every simplicial group is a Kan complex. In case you aren’t familiar with the terminology, let me explain. A simplicial group is a functor where is the simplex category. A Kan complex is a simplial set (i.e., a functor such that for any […]. Written by Sanath Devalapurkar. December 14, 2016. Suppose i...

List of blog posts. A blog about math. Written by Sanath Devalapurkar. June 28, 2016. Chromatic Homotopy Theory – II. Let’s pick up from where we were before. Just to recall, in the previous post, we showed that every complex-oriented cohomology theory gives rise to a formal group law over . In addition, formal group laws are classified by the Lazard ring , that is isomorphic as a graded ring to , so every complex […]. Written by Sanath Devalapurkar. June 26, 2016. June 26, 2016.

A solution to the fun question in the last post – ErdosNinth

List of blog posts. A blog about math. Written by Sanath Devalapurkar. December 14, 2016. December 14, 2016. A solution to the fun question in the last post. First we try the standard methods; the rational root test shows that there aren’t any rational roots. Also, you can’t use Eisenstein here. So we’ll resort to Galois theory :o). We will prove the required result for. To prove irreducibility over. We use Galois theory, by generalizing the same argument used to prove that. Is irreducible (this is case.
An Injective Tango! (Schroeder-Bernstein Theorem) – ErdosNinth
https://erdosninth.wordpress.com/2016/08/24/an-injective-tango-schroeder-bernstein-theorem
List of blog posts. A blog about math. August 24, 2016. August 24, 2016. Now there’s a simple theorem in set theory whose proof has always appeared a bit cloudy to me, since I’ve never been able to find it written in a straightforward manner. This theorem is the Schroeder-Bernstein Theorem. Whose statement is utterly intuitive:. Be sets. If there exists an injection. That is, the two sets have the same cardinality. Test this yourself with a couple of examples. So what are we to do? How do we prove that.

Groupoids | Gentzen translated

Reversibility of binary relations, substochastic matrices, and partial functions. On Zeros of a Polynomial in a Finite Grid: the Alon-Furedi bound →. August 3, 2015. My current top candidate for a mathematical concept that should be and is not (as far as I can tell) consistently taught at the advanced undergraduate / beginning graduate level is the notion of a groupoid. Today’s post is a very brief introduction to groupoids together with some suggestions for further reading. 1,848 more words. The more tr...

Algebraic characterizations of inverse semigroups and strongly regular rings →. Gentzen’s consistency proof is more impressive than you expect. December 5, 2013. I recently said something. About the impossibility to prove the consistency of PA, and that Gentzen proved just this in 1936. Because I got critizised quite a bit, and realized that even famous mathematicians get critizized.

Gentzen’s consistency proof is more impressive than you expect. Reversibility of binary relations, substochastic matrices, and partial functions →. Algebraic characterizations of inverse semigroups and strongly regular rings. December 6, 2014. A good place to learn about inverse semigroups are Tero Harju’s Lecture Notes on Semigroups.

Algebraic characterizations of inverse semigroups and strongly regular rings. Reversibility of binary relations, substochastic matrices, and partial functions. March 22, 2015. After the last post, I decided that the next post should contain images. Next I decided that the time to publish another post has come. Here is an image of an acceptor finite-state machine. Parsing the string “nice”. How can we revert this machine, such that it parses the string “ecin”? Is a very nice book. Its chapter 7. Similarit...

This blog is devoted to my notes on homotopy theory. Intel STS, Day 4. April 30, 2016. I’m Sanath Devalapurkar, an undergraduate at MIT starting Fall 2016. I love mathematics. I have conducted some research in algebraic topology under Marcy Robertson at UCLA, where I have taken some classes. My academic webpage is here. I do not post frequently on this blog anymore, but do post semi-frequently on a group (some friends from the math category at ISEF ’15) blog here: erdosninth.wordpress.com.

This blog is devoted to my notes on homotopy theory. I think that the best way to study mathematics is through interactions with others studying similar things. For those who don’t live near a university, or simply feel like you want to meet more people and talk to them about math, here are some nice links:. No, I’m serious. Gmail is an amazing way to talk to mathematicians; I’ve talked to many using just this one resource! Leave a Reply Cancel reply. Enter your comment here. Address never made public).
