👉 In the context of mathematics, "freers" can refer to two distinct concepts:
1.
Frechet derivative
: In functional analysis and calculus, a Frechet derivative is an important concept that describes how the rate of change of one function with respect to another changes under small perturbations in the former.
2.
Frechet space
: A Frechet space is a mathematical structure where every pair of elements can be compared using a metric (a measure). This allows for compactness and completeness
