I think that the case when the mass distribution on the circle has rotational symmetry is completely different from the case when it...

The angular velocity of the ball changes its direction relative to the ball-fixed frame (see the text attached) and thus it changes its...

This contradicts the formulas attached.

here is my analysis

It's a bit funny because I have equations written down and you're just saying words :)

No!

This does not follow from anything. The ball is a rigid body with a fixed point, and thus it has three degrees of freedom. It is not...

The ball has three degrees of freedom

I composed a problem and initially thought it could be solved by purely analytical means, but it turns out it cannot. The problem is as...

I would like to share a concise proof of the Poincaré Lemma Theorem (Poincaré Lemma) Assume that a smooth ##k##-form...

I haven't checked it out myself, but I trust you.

1. Transport of Differential Forms Let ##M## be a smooth manifold with local coordinates ##x=(x^{1},\dots,x^{m})^{T}##. Consider a...

No, I haven't seen this paper. Thank you. I’m not an expert in algorithm theory and math. logic, but it seems he is addressing a...

The goal of this post is to formally construct the theory of elementary functions without gaps, from the perspective of a...
