Hilbert-Kunz series, F-signature series, and weak p-fractals
Alessio Caminata, Francesco Zerman
We extend the theory of -fractals of Monsky and Teixeira by introducing the notion of weak -fractal. We prove that for a hypersurface having rational Hilbert-Kunz series…

Simplices osculating rational normal curves
Alessio Caminata, Enrico Carlini, Luca Schaffler
A classical result of von Staudt states that if eight planes osculate a twisted cubic curve and we divide them into two groups of four, then the eight vertices of the corresponding…
