Cauchy"s hypothesis or Noll"s theorem claims that $vect(vecX,t;partial Omega) = vect(vecX,t;vecN)$ wherein $vecN$ is the external unity common to the positively oriented surface ar $partial Omega$. This equates to words together the dependence of the surface interaction vector on the surface ar on which that acts is just through the normal $vecN$. My inquiry is what is the definition of the semicolon (;)? how does it differ from the comma (,) offered to separated the function"s very first two arguments?

A semicolon is offered to different variables native parameters. Quite often, the terms variables and parameters are offered interchangeably, but with a semicolon the meaning is that us are specifying a role of the parameters that returns a duty of the variables.

For example, if I compose $f(x1,x2,ldots;p1,p2,ldots)$ climate I median that by offering the parameters $(p1, p2,ldots)$, I create a brand-new function whose arguments are $(x1, x2,ldots)$.

So the general syntax is $functionname(variables;parameters)$.

In Noll"s to organize it says that the role created by giving $partial Omega$ is the same as that developed by offering $vecN$. That"s rather a nice way of saying the the function created only depends on $vecN$.

There is no hard sdrta.netematical difference between the comma (,) and the semicolon(;).

The semicolon is used occasionally to optically different some change group. Therefore the semicolon is not an ext than a reading aid.

The case can be contrasted to the intake of different kind of parentheses, to make complex nestings an ext readable.
