Petra Wittbold

Prof. Dr. Petra Wittbold is a Professor at the Faculty of Mathematics, University of Duisburg-Essen. Her research focuses on nonlinear partial differential equations and applied functional analysis, with applications in analysis, numerical mathematics, and probability theory. She has taught courses such as Functional Analysis, Ordinary Differential Equations, and Evolution Equations across multiple semesters since 2016, emphasizing infinite-dimensional normed spaces, Banach spaces, and nonlinear mappings.

Administratively, she has served as a member of the Examination Board for Bachelor programs in Mathematics, Technomathematics, and Business Mathematics, and as Equal Opportunities Officer of the Faculty of Mathematics (2012–2020). Her recent publications address entropy solutions for fractional porous medium equations, stochastic perturbations in PDEs, and doubly nonlinear equations, reflecting her expertise in nonlinear functional analysis and mathematical modeling.

Her courses often integrate theoretical concepts (e.g., spectral decomposition, compactness, and Hille-Yosida theorem) with practical applications in physics, biology, and society. She collaborates with peers like Britta Berndtsen (secretary) and has supervised seminars on topics including Fourier analysis, operator theory, and nonlinear dynamics.
