Potential theory. A branch of mathematics and mathematical physics that studies the properties of partial differential equations using potentials. In mathematics, a potential is a specific type of integral; in physics, it is an energy-related characteristic of a field. Potential theory serves as the mathematical foundation for field modeling, network analysis, and cryptographic security. Cryptography specifically employs a discrete analogue of potential theory—namely, potential theory on graphs and the related theory of random walks. These concepts are used to ensure the robustness of cryptographic graphs, analyze hash functions, and more. https://t.co/J0AEI42JNk
