Book Description
This volume was published in honor of Rocco De Nicola’s 65th birthday. The Festschrift volume contains 27 papers written by close collaborators and friends of Rocco De Nicola and was presented to Rocco on the 1st of July 2019 during a two-day symposium held in Lucca, Italy. The papers present many research ideas that have been influenced by Rocco's work. They testify his intellectual curiosity, versatility and tireless research activity, and provide an overview of further developments to come. The volume consists of six sections. The first one contains a laudation illustrating the distinguished career and the main scientific contributions by Rocco and a witness of working experiences with Rocco. The remaining five sections comprise scientific papers related to specific research interests of Rocco and are ordered according to his scientific evolution: Observational Semantics; Logics and Types; Coordination Models and Languages; Distributed Systems Modelling; Security.

Book Description
Professor Nicholas N Govorun, corresponding member of the USSR Academy of Sciences, was the principal organizer of the precedent meetings held at Dubna (1979, 1983, 1985). Unfortunately, he passed away in 1989. This volume is to honor his support in Computer Algebra.This is perhaps the only meeting of the entire soviet union computer algebra community and foreign scientists. The meeting presented scientific results, plans for research facilities, and status reports of the basic areas of investigations. The fields covered include computer algebra systems and general algorithms as well as applied algorithms, programs and results in computer algebra applications (mainly in physics).

Book Description
The Kepler conjecture, one of geometry's oldest unsolved problems, was formulated in 1611 by Johannes Kepler and mentioned by Hilbert in his famous 1900 problem list. The Kepler conjecture states that the densest packing of three-dimensional Euclidean space by equal spheres is attained by the “cannonball" packing. In a landmark result, this was proved by Thomas C. Hales and Samuel P. Ferguson, using an analytic argument completed with extensive use of computers. This book centers around six papers, presenting the detailed proof of the Kepler conjecture given by Hales and Ferguson, published in 2006 in a special issue of Discrete & Computational Geometry. Further supporting material is also presented: a follow-up paper of Hales et al (2010) revising the proof, and describing progress towards a formal proof of the Kepler conjecture. For historical reasons, this book also includes two early papers of Hales that indicate his original approach to the conjecture. The editor's two introductory chapters situate the conjecture in a broader historical and mathematical context. These chapters provide a valuable perspective and are a key feature of this work.

Book Description
This book constitutes the refereed proceedings of the 6th FIP WG 2.2 International Conference, TCS 2010, held as a part of the 21th World Computer Congress, WCC 2010, in Brisbane, Australia, in September 2010. The 23 revised full papers presented, together with 4 invited talks, were carefully reviewed and selected from 39 submissions. TCS 2010 deals with topics focused at but not limited to algorithms, complexity, models of computation, logic, semantics, specification and verification, power-awareness issues in wireless networks, data mining, knowledge discovery, multiprocessor issues as well as AI issues.

Book Description
The topics of this thesis are the modal μ-calculus and parity games. The modal μ-calculus is a common logic for model-checking in computer science. The model-checking problem of the modal μ-calculus is polynomial time equivalent to solving parity games, a 2-player game on labeled directed graphs. We present the first FPT algorithms (fixed-parameter tractable) for the model-checking problem of the modal μ-calculus on restricted classes of graphs, specifically on classes of bounded Kelly-width or bounded DAG-width. In this process we also prove a general decomposition theorem for the modal μ-calculus and define a useful notion of type for this logic. Then, assuming a class of parity games has a polynomial time algorithm solving it, we consider the problem of extending this algorithm to larger classes of parity games. In particular, we show that joining games, pasting games, or adding single vertices preserves polynomial-time solvability. It follows that parity games can be solved in polynomial time if their underlying undirected graph is a tournament, a complete bipartite graph, or a block graph. In the last chapter we present the first non-trivial formal proof about parity games. We explain a formal proof of positional determinacy of parity games in the proof assistant Isabelle/HOL. Die Themen dieser Dissertation sind der modale μ-Kalkül und Paritätsspiele. Der modale μ-Kalkül ist eine häufig eingesetzte Logik im Bereich des Model-Checkings in der Informatik. Das Model-Checking-Problem des modalen μ-Kalküls ist polynomialzeitäquivalent zum Lösen von Paritätsspielen, einem 2-Spielerspiel auf beschrifteten, gerichteten Graphen. Wir präsentieren die ersten FPT-Algorithmen (fixed-parameter tractable) für das Model-Checking-Problem des modalen μ-Kalküls auf Klassen von Graphen mit beschränkter Kelly-Weite oder beschränkter DAG-Weite. Für diesen Zweck beweisen wir einen allgemeineren Zerlegungssatz für den modalen μ-Kalkül und stellen eine nützliche Definition von Typen für diese Logik vor. Angenommen, eine Klasse von Paritätsspielen hat einen Polynomialzeit-Lösungs-Algorithmus, betrachten wir danach das Problem, diese Klassen zu erweitern auf eine Weise, sodass Polynomialzeit-Lösbarkeit erhalten bleibt. Wir zeigen, dass dies beim Join von Paritätsspielen, beim Pasting und beim Hinzufügen einzelner Knoten der Fall ist. Wir folgern daraus, dass das Lösen von Paritätsspielen in Polynomialzeit möglich ist, falls der unterliegende ungerichtete Graph ein Tournament, ein vollständiger bipartiter Graph oder ein Blockgraph ist. Im letzten Kapitel präsentieren wir den ersten nicht-trivialen formalen Beweis über Paritätsspiele. Wir stellen einen formalen Beweis für die positionale Determiniertheit von Paritätsspielen im Beweis-Assistenten Isabelle/HOL vor.

Book Description
An Introduction to Formal Languages & Automata provides an excellent presentation of the material that is essential to an introductory theory of computation course. The text was designed to familiarize students with the foundations & principles of computer science & to strengthen the students' ability to carry out formal & rigorous mathematical argument. Employing a problem-solving approach, the text provides students insight into the course material by stressing intuitive motivation & illustration of ideas through straightforward explanations & solid mathematical proofs. By emphasizing learning through problem solving, students learn the material primarily through problem-type illustrative examples that show the motivation behind the concepts, as well as their connection to the theorems & definitions.
