This volume gathers selected papers presented at the Fourth Asian Workshop on Philosophical Logic, held in Beijing in October 2018. The contributions cover a wide variety of topics in modal logic (epistemic logic, temporal logic and dynamic logic), proof theory, algebraic logic, game logics, and philosophical foundations of logic. They also reflect the interdisciplinary nature of logic – a subject that has been studied in fields as diverse as philosophy, linguistics, mathematics, computer science and artificial intelligence. More specifically. The book also presents the latest developments in logic both in Asia and beyond.

Edited in collaboration with FoLLI, the Association of Logic, Language and Information this book constitutes the refereed proceedings of the 27th Workshop on Logic, Language, Information and Communication, WoLLIC 2021, Virtual Event, in October 2021. The 25 full papers presented included 6 invited lectures were fully reviewed and selected from 50 submissions. The idea is to have a forum which is large enough in the number of possible interactions between logic and the sciences related to information and computation.

This book constitutes the revised selected papers of the 5th International Workshop on Dynamic Logic. New Trends and Applications, DaLí 2023, held in Tbilisi, Georgia, during September 15–16, 2023. The 8 full papers in this book were carefully reviewed and selected from 10 submissions. They deal with new trends and applications in the area of Dynamic Logic.

Dynamic Epistemic Logic is the logic of knowledge change. This book provides various logics to support such formal specifications, including proof systems. Concrete examples and epistemic puzzles enliven the exposition. The book also offers exercises with answers. It is suitable for graduate courses in logic. Many examples, exercises, and thorough completeness proofs and expressivity results are included. A companion web page offers slides for lecturers and exams for further practice.

This book illustrates the program of Logical-Informational Dynamics. Rational agents exploit the information available in the world in delicate ways, adopt a wide range of epistemic attitudes, and in that process, constantly change the world itself. Logical-Informational Dynamics is about logical systems putting such activities at center stage, focusing on the events by which we acquire information and change attitudes. Its contributions show many current logics of information and change at work, often in multi-agent settings where social behavior is essential, and often stressing Johan van Benthem's pioneering work in establishing this program. However, this is not a Festschrift, but a rich tapestry for a field with a wealth of strands of its own. The reader will see the state of the art in such topics as information update, belief change, preference, learning over time, and strategic interaction in games. Moreover, no tight boundary has been enforced, and some chapters add more general mathematical or philosophical foundations or links to current trends in computer science. The theme of this book lies at the interface of many disciplines. Logic is the main methodology, but the various chapters cross easily between mathematics, computer science, philosophy, linguistics, cognitive and social sciences, while also ranging from pure theory to empirical work. Accordingly, the authors of this book represent a wide variety of original thinkers from different research communities. And their interconnected themes challenge at the same time how we think of logic, philosophy and computation. Thus, very much in line with van Benthem's work over many decades, the volume shows how all these disciplines form a natural unity in the perspective of dynamic logicians (broadly conceived) exploring their new themes today. And at the same time, in doing so, it offers a broader conception of logic with a certain grandeur, moving its horizons beyond the traditional study of consequence relations.

Edited in collaboration with FoLLI, the Association of Logic, Language and Information this book constitutes the refereed proceedings of the Second Interdisciplinary Workshop on Logic, Language, and Meaning, TLLM 2020, held in Tsinghua, China, in December 2020. The 12 full papers together presented were fully reviewed and selected from 40 submissions. Due to COVID-19 the workshop will be held online. The workshop covers a wide range of topics where monotonicity is discussed in the context of logic, causality, belief revision, quantification, polarity, syntax, comparatives, and various semantic phenomena in particular languages.

Provides a coherent overview of the theory of single population dynamics, discussing concepts such as population variability, population stability, population viability/persistence, and harvest yield while later chapters address specific applications to conservation and management.

The one world problem has been central to knowledge for ages. Of many approaches none has resolved the problem. With great increases in knowledge there is now sufficient ideas, concepts and means to show a unified ultimate totality. Actual Totality is a book whose proofs and detail provide the needed resolution. The approach to unity is by forty types of proof from non-existence to their combined sum. It features those universals, qualities, continua, kinds, and varieties of actual totality whose proofs are most certain. Certainty of proofs produces axioms that are most recognizable as laws. Each type of proof has different laws whose integration and representation give excellent proof of actual totality. Dependence on the observer observed relationship is the basis for relativity. Dependence on the definite absolute quality of the human mind and person is the basis for the absoluteness seen in identity and self-preservation. Mind and matter are part of a continuum that is the basis and proof of actual totality. Many other continuums make up actual totality, including general and special, mass energy, length, time, static and dynamic. The continua are dualities whose spectra form gradients. It is these gradients that make up much of the detail and differential whose vertical integration proves actual totality. The physical universe and the relative universe of civilization, best human life and mind are large components of the general to special spectrum and varieties of actual totality. There is massive interaction and potential to actual existence in and out of actual totality. This occurs with increasing time. In the near to mid-term actual totality is stable, and can be treated as a closed set. In the far term both the actual and potential of actual totality undergo adaptation and alteration that best suits their existence with change. With good representation an overview of the difference between actual totality as a stable and relatively exclusive world and potential changes in the long term become clear. The many revolutions that accompany change and the role of language, math, proportions, geometry, design, propelling and compelling forces that determine creation and evolution of life all reveal proofs of actual totality. The core of actual totality, or actual totality proper, is centered on the here and now that proves unity in totality. The individual, groups, and lives of all people more or less contribute to the whole depending on productivity that is most beneficial to the whole. This is largely dependent on knowledge, and its kinds. Universal knowledge of the highest kind is the great dynamo of advancing actual totality. How well actual totality supplies this need is the most important problem and solution of the next hundreds to thousands of years. It is survival over extinction whose success will depend largely on proactive planning, prevention, preparation, management and control. They can be used to guide each and all persons to a better unified world, by actual totality.

This LNCS book is part of the FOLLI book series and constitutes the proceedings of the 7th International Workshop on Logic, Rationality, and Interaction, LORI 2019, held in Chongqing, China, in October 2019.
