An alphabet is a set (with a linear order) and its elements are called letters.By Σ∗ we denote the free monoid over Σand its elements are called words.For a word w ∈ Σ∗ we denote by w its length and if a ∈ Σ, then w a counts how often the letter aappears in w. Thus, w = P a∈Σ w a.By alph(w) = {a∈ Σ w a ≥ 1} we denote the …

http://www.columbia.edu/itc/sipa/math/nonlinear.html Suppose f : R → R is a function such that each of its first-order partial derivatives exist on R . This function takes a point x ∈ R as input and produces the vector f(x) ∈ R as output. Then the Jacobian matrix of f is defined to be an m×n matrix, denoted by J, whose (i,j)th entry is , or explicitly where is the transpose (row vector) of the gradient of the component.
