ELI5: Explain Like I'm 5

Quasisymmetric function

So, imagine you have some stickers, and you want to put them on a piece of paper. You have many different types of stickers, some big, some small, some with stars on them, some with hearts on them, and so on.

A quasisymmetric function is kind of like a rule you can use to make a cool, symmetrical design with your stickers. It’s like a recipe for making a design that looks nice and balanced.

But, there are a few rules you need to follow when making this design. For example, you need to make sure that the same type of sticker is used in equal amounts on both sides of the design. You also need to make sure that if you move some stickers around, the design still looks the same.

It’s like creating a really pretty pattern with your stickers, but you have to follow some special rules to make sure it’s quasisymmetric!
