Abstract The fast growing solutions of the following linear differential equation $$(*)$$ ( ∗ ) is investigated by using a more general scale $${[p,q]_{,\varphi }}$$ [ p , <mml:m...

Complex networks have become the main paradigm for modelling dynamics of interacting systems. However, are intrinsically limited to describing pairwise interactions, whereas real-world systems often characterized by higher-order interactions involving groups three or more units. Higher-order structures, such as hypergraphs and simplicial complexes, therefore a better tool map real organization ...

In insulating lanthanides, unquenched orbital momentum and weak crystal-field (CF) splitting of the atomic $J$ multiplet at lanthanide ions result in a highly ranked (multipolar) exchange interaction between them complex low-temperature magnetic order not fully uncovered by experiment. Explicitly correlated {\it ab initio } methods proved to be efficient for an accurate description CF multiplet...
