Abstract:

This project is concerned with the mathematical treatment of generalized nonlinear Fokker-Planck equations (well-posedness, asymptotic behavior, approximation and controllability) and their applications to statistical physics, mathematical biology and technique of image processing. Nonlinear Fokker-Planck equations are widely used in statistical physics to describing the anomalous diffusion and open systems far from equilibrium. Several equations arising in Bose-Einstein diffusion, Fermi-Dirac statistics and thermostatistics are of this form. The solutions to these equations represent probability densities of stochastic equations which describe the random dynamics of particles and there exist an equivalent representation of nonlinear Fokker-Planck equations in terms of stochastic differential equations (McKean-Vlasov equations). However, a rigorous mathematical treatment of the existence and longtime behavior of solutions to these equations is missing and this is the main objective of this project which continues a research developed by the principal investigator (V. Barbu) at University of Bielefeld (Germany) in the framework of a scientific project funded by DFG in the period 2017-2021. A large part of this project will be devoted to applications in biology, fluid dynamics and new image processing techniques based on nonlinear Fokker-Planck equations.

The aim of this project is to study a class of bilinear control problems associated to nonlinear stochastic Schrödinger equations with multiplicative Gaussian noise. Some classes of nonlinear diffusion equations (deterministic and stochastic) with applications in Biology and the image restoring technique will also be studied.

Abstract:

Our project's purpose is to develop a novel differential model-based image restoration system that implements diffusion equation-based denoising and reconstruction techniques and integrates them into complex hybrid restoration schemes. Some linear PDE-based smoothing algorithms improving current linear diffusion methods and outperforming conventional 2D filters are modeled first. Then we model both individual and hybrid nonlinear isotropic/anisotropic diffusion approaches that remove the noise and overcome undesired effects. Our second-order parabolic denoising models aim to remove the blurring effect and outperform the state-of-the-art anisotropic diffusion schemes. We also propose fourth-order PDE smoothing techniques that remove sucesfully the staircase effect and outperform existing 4th-order isotropic diffusion models. Novel hybrid PDE schemes combining second and fourth order diffusions are developed in order to achieve optimal restoration, avoid the unintended effects and remove potential speckle noise. The proposed diffusion-based methods may be derived from the associated PDE variational models that are also investigated. Variational inpainting approaches derived from denoising PDEs are then proposed. Besides the deterministic differential models, we consider robust stochastic models for image restoration. Our SDE-based denoising solutions reduce to diffusion models through associated Kolmogorov equations. Rigorous mathematical treatments are provided for all models.

Abstract:

This research project is concerned with the study of the qualitative properties of deterministic and stochastic nonlinear dynamic diffusion equations with a main emphasis on the existence theory in the case of singular diffusion coefficients, localization of solutions, controllability and stabilization. The applications to image processing and description of self-organized criticality of physical processes will be stressed.

The problems considered here are open and in the first line of mathematical research in the field and important for understanding the dynamics of nonlinear diffusion processes perturbed by Gaussian noises. They continue a research line developed in the recent years by the principal investigator and his associates from Romania and abroad. The investigation methods to be used here are new into this context and likely will lead to several new and spectacular results.
