The Gaussian free field (GFF) is a mathematical object commonly studied in the fields of probability theory, statistical mechanics, and quantum field theory. It serves as a foundational model for understanding various phenomena in physics and mathematics due to its intrinsic properties and connections to Gaussian processes.
