After 1971 Novikov became interested in mathematical physics and dynamical systems . He studied a wide variety of applications of mathematics such as dynamical systems in the theory of homogeneous cosmological models, the theory of solitons, the spectral theory of linear operators, quantum field theory and string theory.
Matapos 1971 Novikov naging interesado sa matematika at physics dynamical system. He-aral ng isang malawak na pagkakaiba-iba ng mga aplikasyon ng matematika tulad ng dynamical sistema ng teorya ng magkakatulad kosmolohiko mga modelo, ang mga teorya ng solitons, ang mga multo teorya ng pahaba operator, quantum field theory at string theory.
