From an old friend, today. Let f be a morphism from a surface to a curve, both projective, irreducible and smooth over C; let L be a line bundle on the surface. Q Is the torsion part of R¹f_*L isomorphic to the torsion part of R¹f_*(L^{\vee}\otimes \omega_f)? A Yes, but not canonically. #MathSky

Thanks for 500 followers! I really appreciate folks reconnecting with my work on Bluesky. Yeehaw!

Bekan the Rose, illustrated for Hit Point Press. An illustrated portrait of a stoat person, wearing a cowboy outfit. Her brown leather vest is embroidered with turquoise, red, and white. She has a red bandanna with roses patterned on it, and holds a dark brown cowboy hat with a pearl on it. On her hip is a rope lasso. She looks very chill and cool.

It is pretty amazing how many words a guy like me who believes so much in brevity, needs to do something as simple as make a column vector.... a column vector of a circuit in a matrix is formed by - 1. write down a column vector of all "0"s that is length = number of edges. 1/4

You may have seen the handy inequality n! ≥ (n/e)ⁿ. I didn't know its proof, at least not this short, beautiful one. It's so elegant.

e^n = sum of n^k/k!, for k =0 to n. Since each summand is positive, the sum is lower bounded by its n-th term, which is n^n/n!. So e^n is greater than n^n/n!, and reorganizing the inequality gives the result.

This hypothesis comes from my observation of videos tending to have a "gradual" progression between frames as compared to cuts where the frames lack any easing into each other. And I asked myself how I could quantify that

000

Bambae @murdochakgae.bsky.social · 24/02/2025

Then again I need to research more about this topic as I'm not confident at the one semester linear algebra course I've been taught.

000

Bambae @murdochakgae.bsky.social · 24/02/2025

My hypothesis is if I were to traverse through each frame as represented by a matrix of pixels and find the norm of the difference of the frame and the frame after it, then the cuts in a video should be represented by timestamps with noticeably higher norms as compared to the rest.

200

Bambae @murdochakgae.bsky.social · 24/02/2025

I have this much more plausible idea of using linear algebra to detect cuts in videos and provide exact time stamps for them. Probably something to do with comparing the linear transformations between frames when they're represented as a matrix of pixel values.
