What is meant by functional derivative?

Click For Summary

Discussion Overview

The discussion revolves around the concept of functional derivatives, seeking clarification on its meaning and context. Participants explore its implications within functional analysis and calculus in infinite-dimensional spaces.

Discussion Character

  • Exploratory, Conceptual clarification

Main Points Raised

  • One participant suggests that a functional derivative may relate to the derivative of a function.
  • Another participant emphasizes the need for more context, indicating that functional analysis involves calculus on infinite-dimensional spaces and may imply a specific type of derivative.
  • A third participant references a Wikipedia article on functional derivatives, noting its complexity.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definition or implications of functional derivatives, with multiple interpretations and a request for further context remaining evident.

Contextual Notes

The discussion lacks specific definitions and examples of functional derivatives, and the complexity of the topic is acknowledged without resolution.

Derivative of a function maybe? =)
 


we need more context. functional analysis is calculus on infinite dimensional spaces. maybe its a derivative in that context.
