Cauchy"s Hypothesis or Noll"s theorem states that $vect(vecX,t;partial Omega) = vect(vecX,t;vecN)$ where $vecN$ is the exterior unity normal to the positively oriented surface $partial Omega$. This converts to words as the dependence of the surconfront interactivity vector on the surconfront on which it acts is just via the normal $vecN$. My question is what is the significance of the semicolon (;)? How does it differ from the comma (,) provided to separated the function"s first 2 arguments?

There is no difficult derekwadsworth.comematical difference in between the comma (,) and also the semicolon(;).

The semicolon is offered sometimes to optically sepaprice some variable group. So the semicolon is not even more than a reading help.

The situation can be compared to the consumption of different kind of parentheses, to make complicated nestings more readable.

A semicolon is offered to sepaprice variables from parameters. Quite often, the terms variables and parameters are used interchangeably, yet through a semicolon the meaning is that we are defining a function of the parameters that returns a role of the variables.

For instance, if I compose $f(x1,x2,ldots;p1,p2,ldots)$ then I suppose that by supplying the parameters $(p1, p2,ldots)$, I develop a new attribute whose disagreements are $(x1, x2,ldots)$.

So the basic syntaxes is $functionname(variables;parameters)$.

In Noll"s theorem it says that the feature developed by giving $partial Omega$ is the exact same as that created by giving $vecN$. That"s fairly a nice way of saying that the attribute developed just counts on $vecN$.
