The relationship btw dielectric strength and temperature

Wiki suggests dielectric strength is temperature dependent, but I've yet to find any math supporting this. I found some math corroborating a relationship between conductivity and temperature, but whether or not there's any causality between conductivity and dielectric strength has eluded me. Any help with solving this mystery is greatly appreciated!

Perform a Google search on the terms ("dielectric strength" "temperature effect" math). One of the cites that may be of use is "Low Temperature and Moisture Effects on Oil-Paper Insulation Dielectric Response in Frequency Domain".
Thank you for the response! I've googled "dielectric strength and temperature dependence" recently and read a few papers researching the phenomena. But few included math measuring the effect of temperature changes on dielectric strength. Could you elucidate the math in the paper you've posted? I found a similar study with math included, but its for the dielectric constant instead of strength. The math can be found in the results section of the paper.
