Finding the derivative of a vector function is a fundamental concept in calculus that extends the idea of differentiation from scalar functions to functions that output vectors. This process is ...

This note studies the optimality conditions of vector optimization problems involving generalized convexity in locally convex spaces. Based upon the concept of Dini set-valued directional derivatives, ...

Mistake: "the derivative of f points in the direction of steepest ascent of f." The introduction of chapter 5 is talking about a univariate function with scalar values. This means its derivative at ...
