Interdisciplinary Conference on Multiple Scale Systems,
Systems with Hysteresis and Fluid Mechanics

We are pleased to announce the multidisciplinary international workshop MURPHYS 2022 organized by the Mathematical Institute of the Silesian University in Opava.

The workshop, devoted to mathematical theory and applications of the multiple scale systems, systems with hysteresis and trends in the dynamical systems will take place near Opava, Czech Republic, May 29th to June 3rd, 2022.

MURPHYS 2022 (Multi-Rate Processes and Hysteresis) is the 10th workshop that continues a series of biennial meetings focused on multiple scale phenomena, singular perturbations, phase transitions, hysteresis phenomena occurring in mathematical, physical, economical, engineering and information systems. The previous workshops were held in Cork, Ireland (2002, 2004, 2006, 2008); Pecs, Hungary (2010); Suceava, Romania (2012), Berlin, Germany (2014) and Barcelona, Spain (2016, 2018).

Our invitation for contributing an invited talk was accepted by professors:

Andreas Amann, PUCC Cork, Ireland
„The Devil's Staircase in the Discrete Preisach Memory Model“

Martin Brokate, Technical University of Munich, Germany
„Derivatives of hysteresis operators“

Giovanni Colombo, University of Padua, Italy
„On the optimal control of Moreau's sweeping process“

Daniele Davino, UniversitĂ  degli studi del Sannio, Benevento, Italy
„Self-similarity and feedback in magnetostrictive devices: the force of modeling"

Dorothee Knees, Universität Kassel, Germany
„Optimal control of rate independent systems“

Klaus Kuhnen, Bosch, Germany
"Advanced magnetic constitutive mappings in electromagnetic field simulations"

Vincenzo Recupero, Polytechnic of Turin, Italy
„Some results on the play operator and sweeping processes"

Dmitrii Rachinskii, The University of Texas at Dallas, USA
„SIR model with transmission rate modeled by the non-ideal relay and the Preisach operator“


Main topics of MURPHYS 2022 include (but are not limited to):

  • hysteresis phenomena
  • multiple scale systems
  • nonlinear systems in general
  • self-organizing systems
  • rate-independent systems and energetic solutions
  • spatially discrete systems
  • singular perturbations
  • switched and multistable systems
  • phase transitions
  • periodic orbits and bifurcation theory
  • piecewise differential equations
  • sweeping processes
  • applications of the above mentioned to physical, chemical, biological and economical sciences, engineering and medicine
  • homogenization

New areas of application are particularly welcome.
