Research
Makarov works in complex analysis and related fields (potential theory, harmonic analysis, spectral theory) as well as on various applications to
complex dynamics
Complex dynamics is the study of dynamical systems defined by Iterated function, iteration of functions on complex number spaces. Complex analytic dynamics is the study of the dynamics of specifically analytic functions.
