$$\boldsymbol{(s,p)}$$ -Valent Functions

2017
We introduce the notion of \((\mathcal{F},p)\)-valent functions. We concentrate in our investigation on the case, where \(\mathcal{F}\) is the class of polynomials of degree at most s. These functions, which we call (s, p)-valent functions, provide a natural generalization of p-valent functions (see Hayman, Multivalent Functions, 2nd ed, Cambridge ...
