This talk explores the quasinormal modes (QNMs) of a five-dimensional scale-dependent black hole with a positive cosmological constant, examining scalar, electromagnetic, and Dirac perturbations. We derive exact analytical solutions within the scale-dependent gravity...

We will discuss properties of ideal φ-summing operators generated by Orlicz spaces. We will show asymptotic estimates of φ-summating norms of finite-dimensional operators as well as diagonal operators between certain Banach sequence spaces. The proof is based on the...
