The site had the following in the homepage, "A place for proofs, examples, and topics I find interesting." I noticed that the web site stated " Mollification and the Product Rule." They also stated " In the abstract study of partial differential equations, we often times throw the concept of weak derivatives. Around as if they acted just like classical derivatives. One such example is the product rule. For example, when studying evolution equations. Time dependent partial differential equations such as the Navier-Stokes equations. Books blow past the following equality. Is some sort of inner product."
