This groundbreaking book exposes the hidden world of Chinese irregular migrants in France, Italy, and the UK. Chinese workers migrating to Europe pay huge sums of money to intermediaries, often leaving them trapped in debt before they even begin their journey. Exposed to various risks during their migratory process, they can arrive in the destination country vulnerable to extreme exploitation and sometimes even forced labor. The book seeks to ...

Factor and fractional graph theory are hot topics on modern mathematics. As a generalization, factor and fractional factor are widely used in many fields related to computer science. In this book, we study some topics on factor and fractional factors. Several bounds are given for the existence of factor and fractional factors avoiding some given graphs. In the first chapter, we list all the concepts and lemmas which we use in this book. In the...

Chemical compounds and drugs are often modeled as graphs where each vertex represents an atom of molecule and covalent bounds between atoms are represented by edges between the corresponding vertices. This graph derived from a chemical compounds is often called its molecular graph and can be different structures. In this book, we determine several important topological indices of polynomials of Wiener index of some widely used chemical structu...
