Example:

* Given some real numbers <math>a_1,\dots,a_k</math> and <math>f(x_1,x_2,\dots,)\in \Lambda</math>, then the substitution <math>x_1=a_1,\dots,x_k=a_k</math> and <math>x_j=0,\forall j>k</math> is a specialization.

* Let <math>f\in \Lambda</math>, then <math>\operatorname{ps}(f):=f(1,q,q^2,q^3,\dots,)</math> is called ''principal specialization''.
