what does the notation

f(theta: Y_1, Y_2.....Y_n) mean?

I believe in this example theta is a parameter of the population sample Y_i.

Does it mean that theta (the parameter itself, say variance or mu) is a function of the population sample? Thanks

No. "theta is a function of the population sample" would be "$\displaystyle u= f(Y_1, Y_2, ..., Y_n)$".

This appears to say "we have a function, f, of theta, for given values of $\displaystyle Y_1$, $\displaystyle Y_2$, $\displaystyle Y_2$".

That is, different samples may give different**functions**of theta, not different theta.
