As time goes on, I grow more disillusioned with quantum field theory.

comment What is the notation for taking negative imaginary values for roots of negative numbers?
But if I put a $\sqrt{x}^*$ in my formula, it will look non-analytic.

comment WKB and asymptotic behavior of second order differential equation
The original Riccati equation is $y'(x) = -\frac{a}{x^{n+2}} y^2(x) + a b^2 \frac{e^{-2x}}{x^{n-1}}$. And there is no harm in choosing $y(1) = 1$ as the initial condition (that was the condition I used to generate the plot).

comment Determinant of a finite-dimensional matrix in terms of trace
Although user`someRandomNumber` gave a very formal (probably correct) answer that I can't understand, this is definitely much simpler and something I can work with. Thank you!

comment Determinant of a finite-dimensional matrix in terms of trace
Ok, there's the Cayley-Hamilton theorem... that should be useful in generating the identities.
