One of the most important issues in the development of software product lines is the elicitation, management, and representation of the variability. In this context, one of the most used instruments is the feature model. But a feature model (due to the open definition of feature) usually contains an amalgamation of various different variability aspects as structural, behavioral, non-functional,...

Incorporating aspect-oriented paradigm to a polymorphically typed functional language enables the declaration of type-scoped advice, in which the effect of an aspect can be harnessed by introducing possibly polymorphic type constraints to the aspect. The amalgamation of aspect orientation and functional programming enables quick behavioral adaption of functions, clear separation of concerns and...

Densely-connected networks are prominent among natural systems, exhibiting structural characteristics often optimized for biological function. To reveal such features in highly-connected networks, we introduce a new network characterization determined by a decomposition of network-connectivity into low-rank and sparse components. Based on these components, we discover a new class of networks we...

We define and study a notion of free wreath product with amalgamation for compact quantum groups. These objects were already introduced in the case duals discrete groups under name “free products pairs” previous work ours. give several equivalent descriptions use them to establish properties like residual finiteness, Haagerup property or smash decomposition.
