Black-hole dynamic laws or laws of black-hole dynamics

Explain  laws of black-hole dynamics or First law of black hole dynamics and Second law of black hole dynamics? 

First law of black hole dynamics:

For interactions among black holes and normal matter, the conservation laws of mass-energy, linear momentum, electric charge, and angular momentum holds. This is related to the first law of thermodynamics.

Second law of black hole dynamics:

With black-hole interactions or interactions among black holes and normal matter, the sum of the surface regions of all black holes included can never diminish. This is related to the second law of thermodynamics, with the surface regions of the black holes being an assess of the entropy of the system.
