Invasive Group A Streptococcal InfectionsTo specify the periodic sequence, you only need to specify the finite subsequence which generates it. For eventually periodic, you‘d need to specify the finite initial segment, and the finite periodic part.

Some Naive Set TheoryThis chapter gives meaning to the notion of size (cardinality) for infinite sets. We define countable and uncountable sets, and introduce Gödel numbering, coding, and diagonalization arguments. These ideas will be recycled throughout the book.

Computational ComplexityThis chapter looks at the basics of computational complexity theory. We examine how to calibrate computation by measuring the amount of time and space a machine uses. We introduce polynomial time and polynomial space. We prove the hierarchy theorems and Blum‘s speedup theorem.

Other Approaches to Coping with Hardness∗We look at several other approaches to coping with intractability. They include approximation algorithms, PTAS’s, average case complexity, smoothed analysis, and generic case complexity. We look at both the positive techniques and the hardness theories.
