Notable references: In mathematics, the surname is associated with Kruzhkov entropy solutions, a foundational concept in the theory of nonlinear hyperbolic conservation laws. Named after a Soviet mathematician, these entropy conditions define admissible weak solutions to certain partial differential equations and help establish existence, uniqueness, and stability results for scalar conservation laws. The term “Kruzhkov entropy solution” is widely used in mathematical literature and applications, including fluid dynamics and traffic flow modeling.
