Sharp Volume-Based Bounds for BMO Functions on Compact Domains and Applications
Marin Mišur
We establish sharp localized bounds for compactly supported functions of bounded mean oscillation (BMO). Classical estimates obtained via the John-Nirenberg inequality bound…

Logarithmic Resonance at Mixed Boundary Junctions in Gradient-Dependent Semilinear Equationsv
Marin Mišur
The regularity of solutions to elliptic partial differential equations degrades severely at mixed Dirichlet-Neumann boundary junctions, characterized classically by an $\mathcal{O}…

Global Second Commutation Lemma
Marin Mišur
We prove the second commutation lemma for the Lebesgue spaces , , on the whole unbounded domain, extending the theory of Tartar (1990) to the…
