Homework Help Overview

The discussion revolves around interpreting a homework question regarding the relationship between Lipschitz continuous functions and α-Hölder continuous functions, specifically questioning whether every Lipschitz continuous function is α-Hölder continuous for every α in the interval (0, 1).

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the definitions of Lipschitz and Hölder continuity, questioning the original poster's assertion that the problem is trivial. They discuss the implications of Lipschitz continuity being a special case of Hölder continuity when α=1 and whether this extends to all α in the specified interval.

Discussion Status

The discussion is active, with participants clarifying definitions and exploring the implications of the problem statement. There is recognition of a potential misunderstanding regarding the range of α and its significance in the context of the question.

Contextual Notes

Participants note the importance of the definitions provided in the homework and question whether the original poster may have misinterpreted the requirements of the problem.

Homework Statement


I only need help interpreting the following:
Show that every Lipschitz continuous function is α-Hölder continuous for
every α ∈ (0, 1
The definition of both is given in the homework so this seems trivial but it's a graduate level class. Am I mising something? Thanks for any help!

Well, what are those definitions? Why do you say this is "trivial"?
 
Well by the definitions, Lipschitz is a special case of α-Hölder when α=1. Since α is contained in the interval (0,1] (which is the interval given for α-Hölder) then by def. every Lipschitz continuous function is α-Hölder continuous.

Your question asked to show that it is α-Hölder continuous for every α ∈ (0, 1], not just for α=1. Unless this was a typo? Yes, Lipschitz implies Hölder of order 1. But does it imply this for all orders less than 1?
 
Ahhh, great! yes your right I see it now. Funny how sometimes one can not see what is right in front of them. Thanks for the help, that's exactly what I needed.
