Let $F$ be a field and let $f(x)\in F[x]$. Denote the splitting field of $f(x)$ by $E$. Denote the roots of $f(x)$ by $\alpha_1,...,\alpha_n$. A polynomial $g(x_1,...,x_n) ∈ F[x_1,...,x_n]$ gives an relation between the roots if $g(α_1,...,α_n) = 0.$ Now let $σ\in Aut_F(E)$, and let $τ$ denote...
Let F be a field. Let $f(x) ∈ F[x]$ be a nonzero polynomial, let $E$ be a splitting field for $f(x)$ over $F$, and let $X$ denote the set of roots of $f(x)$ in E Let $f(x)\in F[x]$, and suppose $f(x) = f_1(x)···f_r(x)$ is the factorization of $f(x)$ into irreducible polynomials in $F[x]$. For each...
I have just created a betting → gambling synonym, and merged the former into the latter. I'm not exactly sold on the usefulness of either tag, but for the time being I guess they are basically talking about the same thing.
People always like to evaluate the variance, but is there any way for variance to be interesting to the gambling game makers? In another word, what is a pratical gambling game that involving some distributions that is relating to variance other than the normal distribution?
