I am interested in Boolean function polynomial/rational exact/approximate/one sided approximate representation, relation to circuit/communication complexity, tools utilized to study Boolean functions (such as combinatorics, analysis, approximation theory, algebra etc).
What are some of the important references, lecture notes and key papers (including survey) in the field of Boolean functions for someone wanting to learn the growth of the area from 80s till today.
Even open problems in the area would be a good introduction as one can usually trace back the literature. One important open problem is sensitivity-block sensitivity conjecture.
