Book review: Multilayer Networks: Structure and Function Ginestra Bianconi | Review by Bogdan Hoanca Taking network analysis to the next step, multilayer networks are sets of different networks that interact among themselves or networks that change dynamically over time (or combinations of the two). As layers interact, links that denote stronger connections can lead to chain events and catastrophic impacts. Capturing this type of behavior allows multilayer networks to model complex systems. Not to be confused with subnetworks in a larger network, the layers in multilayer architectures tend to be different from each other. The book starts with the basics of single-layer networks but quickly moves into more challenging multilayer network concepts. Math that may seem complex at first is mostly sums and products (some with quite complex nesting). There are also elements of more challenging linear algebra and bits of calculus here and there. The book is illustrated with a wealth of char...
