Dedekind numbers and related sequences

This thesis considers Dedekind numbers, where the nth Dedekind number D(n) is defined as the number of monotone Boolean functions (MBFs) on n variables, and R(n), which counts non-equivalent MBFs. The values of D(n) and R(n) are known for up to n = 8 and n = 6, respectively; in this thesis we propose a strategy to compute R(7) by considering profile vectors of monotone Boolean functions. The profile of an MBF is a vector that encodes the number of minimal terms it has with 1,2,...,n elements. The computation is accomplished by first generating all profile vectors of 7-variable MBFs, and then counting the functions that satisfy each one by building up from scratch and taking disjunctions one by one. As a consequence of this result, we will be able to extend some sequences on the Online Encyclopedia of Integer Sequences, notably R(n) up to n = 7, using only modest computational resources.
