critical exponent

[′krid·ə·kəl ik′spō·nənt]
(thermodynamics)
A parameter n that characterizes the temperature dependence of a thermodynamic property of a substance near its critical point; the temperature dependence has the form | T-Tc | n , where T is the temperature and Tc is the critical temperature.

In fact, in combinatorics and in statistical physics, most of the asymptotics of integer sequences are of the shape [b.sub.n] ~ C[n.sup.[alpha]] [A.sup.n], and the exponent [alpha] which appears there is a key quantity: its value is often the signature of some universal phenomena (in physics, it is called a critical exponent).

Let [k.sub.c]: = min{k [member of] Z - {0}|[a.sub.k] [not equal to] 0}, then [alpha] = [k.sub.c]/N is called the critical exponent (loosely speaking, [alpha] is the "first non zero exponent" appearing in the series, and if [z.sub.0] is not precised, it is by default the radius of convergence of f(z)).
where [phi] is the volume fraction of filler, [p.sub.c] is the percolation threshold of filler, [[rho].sub.f] is the resistivity of the filler, [r.sub.l] is the resistivity of the polymer or matrix, and p is the critical exponent which represents the volume fraction of the phases.
