Mixed perverse sheaf
A mixed perverse sheaf is like a special type of bundle made up of little pieces of data, which can help us understand complicated geometric objects. Imagine you have a puzzle with many pieces, but you don't know how they fit together. A mixed perverse sheaf can help you figure out how different parts of the puzzle fit together!
First, let's talk about what a "perverse sheaf" is. It's like a bundle of information that tells us about a shape or object, but it's not just any old bundle. It's special because it contains data that can help tell us how the object is put together. It's like a map that tells us about all the different parts and how they relate to each other.
Now, let's add in the "mixed" part. A mixed perverse sheaf is a bundle of information that contains different types of data, or "grades". Just like in school, there are different grades that tell us how well we're doing. In a mixed perverse sheaf, each grade tells us something different about the shape or object we're studying.
But why is this useful? Well, sometimes shapes and objects can have really complicated structures or might be made up of many different pieces. The different grades in the mixed perverse sheaf can help us break down this complicated structure into simpler pieces that we can understand and work with. It's like taking a really big, confusing puzzle and breaking it down into smaller, more manageable pieces.
So, to sum it up, a mixed perverse sheaf is a special bundle of information that tells us about a shape or object, but it's special because it contains different grades of data that can help us break down the complicated structure of the object into simpler pieces that we can understand.
