Kodaira vanishing theorem

Kodaira vanishing theorem is like a special rule that helps mathematicians figure out things about shapes. It says that if you have something like a round donut shape, then mathematicians can figure out how much it can bend or twist. It is like when you have a piece of paper and you can fold or twist it lots of different ways - kodaira vanishing theorem helps mathematicians figure out how far you can go before the shape changes.
