Ján Lang works in mathematical analysis, focusing on how function spaces (such as Sobolev, Lebesgue, and Lorentz spaces) relate to one another through mappings called embeddings, and on measuring how 'non-compact' or 'singular' these mappings and related transforms (like the Fourier and Laplace transforms) are. This work sits within functional analysis and operator theory, and has connections to partial differential equations. Some recent outputs also involve applied topics like educational technology and personalized learning systems, though the core research remains in pure mathematics.
