comment Relation between runge domain and polynomial convexity
@GeorgesElencwajg, can you look at the comment below your answer? Why does the article claim that these two concepts are equivalent? link.springer.com/content/pdf/10.1007%2FBF01420524.pdf in the first sentence he says "In [1] we gave an example of a domain in $\mathbb{C}^3$ which is analytically equivalent to the polycyclinder in $\mathbb{C}^3$, but which is not a Runge domain." and links to ""An example concerning polynomial convexity". I am still confused

I agree with you, I am very new to this subject so sorry for coming of as arrogant.

comment Relation between runge domain and polynomial convexity
Thank you =) Is it clear from the paper link.springer.com/content/pdf/10.1007%2FBF01420524.pdf that the bounded domain should also be polynomialy convex (and if not is there a way to prove it)?

comment Relation between runge domain and polynomial convexity
@GeorgesElencwajg I agree with the strict equality sign, but what do you mean by your second comment? I took the definition straight from here encyclopediaofmath.org/index.php/Polynomial_convexity.

comment Where to find interesting integrals for a Calc III student?
math.stackexchange.com/questions/765198/… Here are some answers. In the link I posted earlier are a large number of semi-hard problems, look at page 11^2 as an example. Basically being good at something boils down to doing it a lot. Once you have solved a few hundred integrals, you will be much more profficient at it.

So basically a constant distribution is $\langle T_f , \phi \rangle = C \int_{-\infty}^\infty f(x)\,\mathrm{d}x$ where the $C$ is dependent on the test function?
