comment What is $\int (1-e^{-x})^n dx$?
$\int(1-e^{-x})^n\,dx=x-\sum_{p=1}^n\tfrac{1}{p}(1-e^{-x})^p$

comment Applications of set theory in physics
the journal may be controversial, but it's the author that counts, isn't it? en.wikipedia.org/wiki/Bruno_Augenstein --- many of these issues have also been addressed here mathoverflow.net/questions/27428/… and here mathoverflow.net/questions/10334/…

comment Applications of set theory in physics
Links between Physics and Set Theory: sciencedirect.com/science/article/pii/S0960077996000550 a rather exhaustive discussion (with over 100 references) has been given by Augenstein in this paper, perhaps you'll want to focus your question a bit on one particular aspect?

comment Expectation of Gaussian random vector & arbitrary function thereof?
you have to evaluate this boundary term at infinity, where it vanishes exponentially fast (assuming f(x) does not blow up at infinity, but then the average is not defined)

comment Geometric interpretation for partial trace?
a physics interpretation is that the partial trace is the way one obtains marginal probability distributions in quantum mechanics: the density matrix $\rho$ describes the probability distribution $P_{X,U}$ of the combined systems $X$ and $U$ and by performing the partial trace over $U$ one obtains a new density matrix $\rho_X$ that describes the marginal distribution $P_X$ of system $X$ alone; this is not the geometric interpretation you are asking for, but I would think that if you have a "geometric interpretation" of the marginal distribution then you're done.

comment inflow/outflow Boundary Conditions for flow in pipe
for a meaningful response form this site, you'll want to formulate your issue as a mathematical problem, rather than "if I do this my program crashes"
