Dirac Measure

A Dirac measure is a mathematical tool used to focus a "weight" or "mass" at a single point within a space. Imagine placing a dot on a map; the Dirac measure assigns all the probability or mass to that specific location, making it "concentrated" there. It’s often used in probability and analysis to model situations where an event or quantity occurs exactly at one point, with no spread or distribution. Essentially, it acts like a spotlight illuminating just one point, leaving everything else unmarked.
