Say you’re given the set , and asked to choose a number. Any number. You may choose , or anything that you feel like from the set. Now suppose you’re given a set , and you have absolutely no idea about what points contains. In this case, you can’t visualize the points in and pickContinue reading “Axiom of Choice- a layman’s explanation.”

## My first attempt at solving the Lonely Runner Conjecture

Let us suppose there are runners running at speeds around a field of circumference . Take any runner from the runners- say , who runs with speed . Say we pair him up with another runner who runs with speed . Then for time , the distance between them is , and for , theContinue reading “My first attempt at solving the Lonely Runner Conjecture”

## Proofs of Sylow’s Theorems in Group Theory- Part 1

I will try to give a breakdown of the proof of Sylow’s theorems in group theory. These theorems can be tricky to understand, and especially retain even if you’ve understood the basic line of argument. 1. Sylow’s First Theorem- If for a prime number , , and , then there is a subgroup such thatContinue reading “Proofs of Sylow’s Theorems in Group Theory- Part 1”

Today, I will discuss this research paper by Javed Ali, Professor of Topology and Analysis, BITS Pilani. What exactly is a proximinal set? It is the set of elements in which for any , you can find the nearest point(s) to it in . More formally, for each such that . This article says aContinue reading

This is the second time I’m checking whether I can write a LATEX equation in wordpress.

## Why I have nothing better to do than blog :(

After trying to follow blogs by various mathematicians, I have concluded that having a digital presence is pretty darned cool and useful in academia! Hence, in my pursuit of the forever-elusive elixir of “cool”, I have decided to record my progress in Algebraic Geometry through this blog. I’m no expert. But I feel trying to explain conceptsContinue reading “Why I have nothing better to do than blog :(“
