Counting subalgebras of $o^{n}$

Aaron Blas Pereda, Diego Sulca

Let $o$ be a compact discrete valuation ring and $n \geq 2$ . We introduce a method to study the cotype zeta function of subalgebras of $o^{n}$ . This multivariabl…

Purely Inseparable ring extensions

Celia del Buey de AndrÃ©s, Diego Sulca

We revisit the concept of special algebras, also known as \textit{purely inseparable ring extensions}. This concept extends the notion of purely inseparable field extensions to the…

Differentiably simple rings and ring extensions defined by $p$ -basis

We review the concept of differentiably simple ring and we give a new proof of Harper's Theorem on the characterization of Noetherian differentiably simple rings in positive charac…
