Blow-up for a semilinear Tricomi equation in the oscillatory regime at the critical Strauss-type exponent

Diego Marcon, Wanderley Nunes do Nascimento, Matheus C. Santos

We study finite-time blow-up for a semilinear shifted Tricomi equation with decreasing propagation speed and an oscillatory scale-invariant mass. We focus on the Strauss-type criti…

Bernoulli problem for the fractional -Laplacian

Rafael Costa, Diego Marcon

We study regularity properties of minimizers for the one-phase Alt--Caffarelli problem associated with the fractional -Laplacian in the range . We consider minimizers of…

Gradient Regularity for Fully Nonlinear Equations with Variable Degeneracy and Hamiltonian Lower-Order Terms

Gleiciano Cosmo, Rafael R. Costa, Diego Marcon

We study local regularity properties of viscosity solutions to fully nonlinear elliptic equations with variable gradient degeneracy and Hamiltonian-type lower-order terms, \[ |\nab…

Blow-up for a Semilinear Tricomi-type Equation with Scale-Invariant Mass in the Oscillatory Regime

Diego Marcon, Wanderley Nascimento, Matheus Santos

We investigate the finite-time blow-up of solutions to a Tricomi-type equation with scale-invariant potential and power nonlinearities in the oscillatory regime. For smooth, compac…

An obstacle problem arising from American options pricing: regularity of solutions

Henrique Borrin, Diego Marcon

We analyse the obstacle problem for the nonlocal parabolic operator \[\partial_t u + (-Δ)^{s} u - b \cdot \nabla u - \mathcal{I}u - ru,\] where , …

On the Lagrangian structure of transport equations: relativistic Vlasov systems

Henrique Borrin, Diego Marcon

We study the Lagrangian structure of relativistic Vlasov systems, such as the relativistic Vlasov-Poisson and the relativistic quasi-eletrostatic limit of Vlasov-Maxwell equations.…

Non-local diffusion with free boundaries

Diego Marcon, Rafayel Teymurazyan

We prove optimal regularity and derive several geometric properties for solutions of a free boundary problem with fractional diffusion. Additionally, we deduce local regu…

Homogenization of obstacle problems in Orlicz-Sobolev spaces

Diego Marcon, José Francisco Rodrigues, Rafayel Teymurazyan

We study the homogenization of obstacle problems in Orlicz-Sobolev spaces for a wide class of monotone operators (possibly degenerate or singular) of the -Laplacian type.…

The calculus of thermodynamical formalism

Paolo Giulietti, Benoit Kloeckner, Artur Lopes +1

Given a finite-to-one map acting on a compact metric space, one classically constructs for each potential in an appropriate Banach space of functionsa transfer operator acting on f…

On the Blow-up Criterion of Magnetohydrodynamics Equations in Homogeneous Sobolev Spaces

Diego Marcon, Wilberclay G. Melo, Lineia Schutz +1

In this paper, we obtain new lower bounds on the Homogeneous Sobolev--norms of the maximal solution of the Magnetohydrodynamics Equations. This gives us some insight on the blow-up…

A quantitative log-Sobolev inequality for a two parameter family of functions

Emanuel Indrei, Diego Marcon

We prove a sharp, dimension-free stability result for the classical logarithmic Sobolev inequality for a two parameter family of functions. Roughly speaking, our family consists of…
