Uniform integrability

Uniform integrability refers to a fancy math concept that basically means that a group of numbers can be added up or integrated in a certain way, and the sum or integral will stay within a certain limit. Imagine you have a bunch of toys in a box, and you want to make sure that no matter how many toys you add up or take away, the total number of toys will always be within a certain range.

So, let's say you have a group of numbers (or toys) that you want to add up, and you want to make sure that the total sum will never get too big. This is where uniform integrability comes in. It tells you that no matter how many numbers (or toys) you have, you can always control the total sum (or number of toys) so that it never gets too big.

Think about it like this: let's say you're playing with blocks, and you want to make a tower. You can add as many blocks as you want, but you don't want the tower to get too tall, or else it might fall over. This is like uniform integrability. It's a way of making sure that you don't add too many blocks (or numbers) and end up with a tower (or sum) that's too big to handle.

In math terms, uniform integrability is a property of a group of numbers that allows you to control the sum or integral of the group, even as the number of numbers in the group gets larger and larger. It's like knowing how many blocks you can add to your tower before it becomes too tall to stand up on its own.
