A point-free approach to the Nakaoka spectrum of a Tambara functor

Drew Heard · 2026

For $G$ a finite group and $T$ a $G$-Tambara functor, we construct the frame $\mathop{RadId}_G(T)$ of radical Tambara ideals and show that its points are the Nakaoka primes. We show that this frame is…

A generalization of the Takagi function for beta-expansions

Shintaro Suzuki · 2026

We consider a generalized Takagi function for beta-expansions with the base $1<\beta\leq2$, motivated by multifractal analysis for digit frequency sets of beta-expansions [20]. We show that it is poin…

Thermodynamic signatures of non-Hermiticity in Dirac materials via quantum capacitance

Juan Pablo Esparza, Francisco J. Pena, Patricio Vargas, Vladimir Juricic · 2026

Non-Hermitian band descriptions capture how loss, gain, and environmental coupling reshape quantum matter, yet most experimental tests rely on wave-based or dynamical probes. Here we establish a new e…
