Mathematical analysis, Uniqueness, Nonlinear system, Conservation law and Weak solution are his primary areas of study. His study on Mathematical analysis is mostly dedicated to connecting different topics, such as Rate of convergence. Kenneth H. Karlsen combines subjects such as Anisotropic diffusion, Compressibility, Polytropic process, Differential equation and Lipschitz continuity with his study of Uniqueness.

The Nonlinear system study combines topics in areas such as Law, Continuous-time stochastic process and Equicontinuity. Kenneth H. Karlsen interconnects Numerical analysis, Uniqueness theorem for Poisson's equation, Compact space and Piecewise in the investigation of issues within Conservation law. The various areas that Kenneth H. Karlsen examines in his Weak solution study include Semigroup, Burgers' equation, Convection and Camassa–Holm equation.
