Is the ISC kaput
Which web address did you try? I just tried this one: oldweb.cecm.sfu.ca/projects/ISC/ISCmain.html and it seems to work fine.

Disruptive innovations in mathematical notations
Don't ever use the word "disruptive" in a proposal! Everybody knows the right word is "transformative"!

A distributional normal derivative for functions in $H^1(\Omega)$
$H^1(\Omega)^*$ is not a space of distributions in $\Omega$. For instance, the functional on the left hand side of your equation is in $H^1(\Omega)^*$. This defeats the objective of separating the inhomogeneous term in the PDE from the boundary condition.

A problem that involves matrix and Lorentz Transformation
You can fill up twodimensional matrices with zeros and make them fourdimensional.

$C^0$ estimate for solutions of elliptic PDE with Neumann BC
If f and h are bounded, they are in every $L^p$. You can then get what you want by using $L^p$ estimates and Sobolev embedding.

Eigenstates of Fourier transformation
I don't see why this makes any difference. Voting to close as a duplicate.

Decay of weak solutions to degenerate parabolic PDEs on manifolds without boundary
Questions like this always leave me with the impression that the poster has not done his/her homework to an appropriate extent. I mean, there are only about a bazillion or so papers in the literature about porous media and similar equations. So in a question like this, I would rather expect something along the lines of: I have read Refs. [1][20], and I have concluded X, but this still leaves Y unanswered.

Solving a non linear equation
Why the votes to close? Is there a simple argument for uniqueness that some of us are missing?

Linear interpolation in weighted Sobolev spaces
How did you prove functions in $W_{2,0}$ are bounded? Did you not do this by showing that the $L^\infty$ norm is bounded in terms of the $W_{2,0}$ norm? You also say you know $C^\infty$ functions are dense. So you have a uniformly convergent sequence of $C^\infty$ functions. This implies the limit is continuous.

Can a monotone exponentially decreasing function be uniformely approximated bt Gaussians?
Then the answer is different and approximation is possible. For instance, you can set $\exp(x^2)=u$ and $f(x)=g(u)$. Now use the Weierstrass approximation theorem to approximate g by a polynomial on the interval [0,1].

Determinant inequality involving Hermitian, positive definite matrices
Why do your expect this to be true? Have you compiled extensive evidence or is this posed somewhere as a problem?
