Valency patterns and valency orientation have been frequent topics of research under different perspectives, often poorly connected. Diachronic studies on these topics is even less systematic than synchronic ones. The papers in this book bring together two strands of research on valency, i.e. the description of valency patterns as worked out in the Leipzig Valency Classes Project (ValPaL), and the assessment of a language's basic valency and its possible orientation. Notably, the ValPaL does not provide diachronic information concerning the valency patterns investigated: one of the aims of the book is to supplement the available data with data from historical stages of languages, in order to make it profitably exploitable for diachronic research. In addition, new research on the diachrony of basic valency and valency alternations can deepen our understanding of mechanisms of language change and of the propensity of languages or language families to exploit different constructional patterns related to transitivity.

In the past few decades, several interesting problems have been solved using fixed point theory. In addition to classical ordinary differential equations and integral equation, researchers also focus on fractional differential equations (FDE) and fractional integral equations (FIE). Indeed, FDE and FIE lead to a better understanding of several physical phenomena, which is why such differential equations have been highly appreciated and explored. We also note the importance of distinct abstract spaces, such as quasi-metric, b-metric, symmetric, partial metric, and dislocated metric. Sometimes, one of these spaces is more suitable for a particular application. Fixed point theory techniques in partial metric spaces have been used to solve classical problems of the semantic and domain theory of computer science. This book contains some very recent theoretical results related to some new types of contraction mappings defined in various types of spaces. There are also studies related to applications of the theoretical findings to mathematical models of specific problems, and their approximate computations. In this sense, this book will contribute to the area and provide directions for further developments in fixed point theory and its applications.
