Big Math and the One-Brain Barrier: A Position Paper and Architecture Proposal Jacques Carette, William M. Farmer, Michael Kohlhase, and Florian Rabe 2019 Abstract Over the last decades, a class of important mathematical results has required an ever increasing amount of human effort to carry out. For some, the help of computers is now indispensable. We analyze the implications of this trend towards big mathematics, its relation to human cognition, and how machine support for big math can be organized. The central contribution of this position paper is an information model for doing mathematics, which posits that humans very efficiently integrate five aspects of mathematics: inference, computation, tabulation, narration, and organization. The challenge for mathematical software systems is to integrate these five aspects in the same way humans do. We include a brief survey of the state of the art from this perspective.
