📢 New preprint: The Biharmonic Heat Equation with General Dynamic Boundary Conditions

https://www.researchgate.net/publication/403976371_The_Biharmonic_Heat_Equation_with_General_Dynamic_Boundary_Conditions

Using semigroup and form methods, we prove the well-posedness of such equations and analyze their main qualitative properties (e.g., self-adjointness, analyticity, compactness, eventual positivity, eventual contractivity).

PDF | In this work, we initiate the study of the biharmonic heat equation in a spatial bounded domain subject to dynamic boundary conditions involving... | Find, read and cite all the research you need on ResearchGate
