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.
