A universal route from avalanches in mean-field models with random fields to stochastic Poisson branching events

Avalanches in mean-field models can be mapped to memoryless branching processes defining a universality class. We present a reduced expression mapping a broad f

Moreover, under a weak Poincaré inequality on the boundary, they show that solvability in Hajłasz-Sobolev spaces is equivalent to stronger solvability in Hardy-Sobolev spaces of tangential derivatives.

What if rearranging a triangle gave you extra area out of nowhere? In this short visual puzzle (youtube.com/shorts/k-i4V...), we break apart a triangle, shuffle the pieces… and a mysterious square appears. Is it magic? A trick?

The Scottish mathematician Peter Guthrie Tait loved to think about knottiness. His atlas of knots shows how hard it can be to tell knots apart. www.quantamagazine.org/a-simple-way...
