Let $\Lambda$ be a finite-dimensional algebra over a field $\mathcal{K}$, let $\mathrm{st}(\Lambda)$ be the stable rank at which the descending powers of the module-category radica…

Let $\Lambda$ be a special biserial algebra with at least one band, and let $\mathrm{st}(\Lambda)$ denote its stable rank. Stable-rank conjecture. The stable rank satisfies … This…

Let $X$ be a compact Hausdorff space, and let $\tau$ be a topological involution of $X$. Denote the set of fixed points of $\tau$ by $E$. The algebra $C(X,\tau)$ is the algebra of…
