Q: Constructive approximation of Lipschitz functions

Valery SaharovThere are a number of theorems in classical functional analysis about approximation of Lipschitz functions by smooth functions. I was wondering if there are any similar constructive (a la Bishop for instance) and explicit results. Namely, if $f$ is a function from a (compact) metric space $(X,\r...

I do not think I will be qualified to give any advice about that. At least I can say that I know almost nothing about constructive mathematics,
BTW I am in a train at the moment, so I am on wifi, so my internet connection is not that reliable. I will definitely not be in chat all the time during the travel.

Have a good trip!
Nope, that was about another question, the one that we discussed recently, but I've already figured it out. It is an interesting fact that the Kirszbraun's extension theorem works only for l-2 metrics
Btw, if you know something about heat kernels, would be still nice if you could provide a reference, no matter if constructive or classical.
