📢 New Chapter: Logarithmic Convexity of Evolution Equations and Application to Inverse Problems, Methusalem Seminars at Ghent Analysis and PDE Center, 2026.

We briefly review recent results on the logarithmic convexity for evolution equations, a well-known method in inverse and ill-posed problems. Some open problems are also mentioned.

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).
