Locally bounded linear differential operators

Click For Summary

Discussion Overview

The discussion revolves around the concept of locally bounded (or locally weakly compact) differential operators within the context of the Schwartz space of smooth functions on a sigma-compact manifold. Participants explore the abstract nature of the problem and its potential connections to the Navier-Stokes equations.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant presents a problem statement regarding locally bounded differential operators, indicating an expectation for an abstract solution.
  • Another participant challenges the initial post by questioning the clarity of the problem and asking for more context about the work done so far.
  • A different participant suggests that the problem relates to the core of the Navier-Stokes equation, referencing their study of bornology and its relevance to boundedness of sets and functions.
  • A subsequent reply reiterates the connection to the Navier-Stokes equation but questions the clarity of the initial problem statement, emphasizing the need for a more defined objective.

Areas of Agreement / Disagreement

Participants express differing views on the clarity and focus of the problem presented. There is no consensus on the specific problem being addressed or its implications related to the Navier-Stokes equation.

Contextual Notes

The discussion highlights a lack of clarity in the initial problem statement, with participants expressing uncertainty about the specific objectives and connections to broader mathematical concepts.

The following is a problem statement.

locally bounded (or locally (weakly) compact) differential operators of the Schwartz space of smooth functions on a sigma-compact manifold

I realize this is very abstract. I expect the solution to be just as abstract.

Thanks in advance.

That's not a question, and we're not in the habit of doing people's work for them anyway. What is the problem you're working on, and what have you done so far?
 
I believe the above problem is the core of the Navier-Stokes equation. It describes the inner working of the NS equations from a mathematical operator's point-of-view.

I have studied bornology from Hogbe-Nlend's books Bornology and Functional Analysis; Nuclear and Conuclear Spaces. According to Wikipedia, bornology is the minimum amount of structure to address boundedness of sets and functions.

The next closest thing I have come across is Nuclear Convex Bornological Spaces.

What problem? You just said a kind of operator. It would be like me starting a thread and saying "bounded linear function". What are you trying to prove?
