Siegel modular variety

Okay kiddo, imagine you have lots of stickers and you want to put them on a piece of paper in a cool and organized way. You start by picking a big square paper, and then you divide it into little squares. Each little square will be a special place where you can only put one sticker.

Now imagine that instead of stickers, we use numbers, specifically complex numbers, which have a real part and an imaginary part. We like these numbers because they help us describe how things move and change over time.

We take those little squares we made before and we organize them in a special way. We call this organization a "modular form." It's like a puzzle that we can solve with those complex numbers we talked about before.

But wait, there's more! We can make lots of different modular forms, each with its own unique puzzle to solve. And when we put them all together, we get something called a "Siegel modular variety."

Think of it like a giant puzzle made up of lots of smaller puzzles. And by solving all these puzzles, we can learn more about how complex numbers work and how things move and change over time.

So there you have it, a Siegel modular variety is like a big puzzle made up of smaller puzzles using complex numbers to help us understand how things move and change.
