Some useful books

I will rely on basic results about computability and complexity that are (usually) covered in a Computer Science undergraduate curriculum. If you need to freshen up on these topics, I can recommend:

• “Introduction to the Theory of Computation”, Sipser, PWS 1997.
• “Introduction to Automata Theory, Languages, and Computability”, Hopcroft, Motwani, and Ullman, 2nd edition, Addison-Wesley 2001.
• “Computational Complexity: A Modern Approach”, Arora and Barak, Cambridge University Press 2009.
• I have also made available my own notes on computability (see above).

There many textbooks on logic but let me recommend my favorites:

• “Logic for Computer Science”, J. Gallier, (Wiley 1986), out of print but available here with the latest revisions.
• “A mathematical introduction to logic”, H. B. Enderton, Harcourt/Academic Press, 1972 and 2000.
• “Introduction to mathematical logic”, E. Mendelson, various publishers, 1964, 1979, 1987, and 1997.
• “Computability and logic”, G. Boolos and R. Jeffrey, Cambridge Univ.~Press, 1974 and 1980.

The complete classification of the prefix fragments of FOL from the point of view of the decidability of satisfiability is in:

• “The Classical Decision Problem”, Boerger, Graedel, and Gurevich, Springer 1997.

The story of how mathematical logic gave birth to computer science is told best in:

• “Engines of Logic: Mathematicians and the Origins of the Computer”, Davis, 2nd edition, Norton 2001.

There are many, many textbooks that offer an introduction to probabilities I prefer those that do a good job on discrete probability spaces. Some examples:

• “Probability and Random Processes”, Grimmett, Stirzaker, Oxford U. Press 2001.
• “Probability: Theory and Examples”, Durrett, Thomson (Brooks/Cole) 2005.
• There is also a brief introduction to probability in chapter 2 of Koller-Friedman (mentioned below).

For 0-1 laws, I will consult

• “Elements of Finite Model Theory”, Libkin, Springer 2004.
• “The Strange Logic of Random Graphs”, Spencer, Springer 2001.

For the logic of independence in Bayesian and Markov networks I will follow selected sections from:

• “Probabilistic Graphical Models”, Koller, Friedman, MIT Press 2009.
