Summary
Ultra-violet Divergence
refers to the problem in
Quantum Field Theory
where integrals over
High-energy modes
lead to
Infinite results
, making
Physical predictions
impossible without a method to handle these infinities. This issue is resolved through renormalization, a process that adjusts the
Parameters of the theory
to
Absorb these infinities
, allowing for finite,
Meaningful predictions
.
