Hyperbolic group
A hyperbolic group is a group that has a special way of being all twisted up, like a big pretzel. Imagine you have a bunch of toys that can stick together in different ways. If you put some of them together in a way that looks like a pretzel or a knot, that's called a hyperbolic shape.
Now, imagine that the toys are numbers or symbols that represent a group. This group can have a special property that makes it look like a hyperbolic shape. This property means that the group is twisted up in a way that you can't easily untangle it. It's like a puzzle that's really hard to solve.
One important thing to know about hyperbolic groups is that they have lots of interesting properties that mathematicians find fascinating. There are many different types of hyperbolic groups, and each one has its own unique shape and properties. But no matter what shape they have, they all have this special property that makes them challenging and exciting to study.
