Hello everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I have recently bumped into the Kramers Kronig Relations while reviewing some of my Eletromagnetism notes, and as you may know those relations are written in terms of theCauchy Principal Value (CPV)of certain integrals. Well, I've never been very familiar with with the concept of aCPV, so I decided to read a little more about it hoping to achieve a better understanding of that idea.

After some reading, as far as I understand, theCPVseems to be just a definition to assign values to integrals that in the first place would be indeterminate - which sounds a bit weird for me. So I was hoping to ask if this is the correct way of thinking about it. Is it really just a funny way of expressing certain values that would be otherwise ill-defined or is there something more to it?

Thank you very much!
