Parabolic equations in Musielak -- Orlicz spaces with discontinuous in time $N$-function

We consider a parabolic PDE with Dirichlet boundary condition and monotone operator $A$ with non-standard growth controlled by an $N$-function depending on time and spatial variable. Expand abstract.

On the rigidity of stationary charged black holes: small perturbations of the non-extremal Kerr-Newman family

We prove a perturbative result concerning the uniqueness of Kerr-Newman family of black holes: given an asymptotically flat space-time with bifurcate horizons, if it agrees with a non-extremal Kerr-Newman space-time asymptotically flat at infinity and it is sufficiently close to the Kerr-Newman family, then the space-time...

Invariant subspaces and exact solutions for some types of scalar and coupled time-space fractional diffusion equations

The effectiveness and applicability of the method have been illustrated through time-space (i) fractional diffusion-convection equation, (ii) fractional reaction-diffusion equation, (iii) fractional diffusion equation with source term, (iv) two-coupled system of the fractional diffusion equation, (v) two-coupled system...

Analysis of amplification mechanisms and cross-frequency interactions in nonlinear flows via the harmonic resolvent

We propose a framework that elucidates the input-output characteristics of flows with complex dynamics arising from nonlinear interactions between different time scales. Expand abstract.

New structures to solve aggregated queries for trips over public transportation networks

We considered a wide range of different queries about the use of the transportation network such as counting-based or aggregate queries regarding the load of any line of the network at different times. Expand abstract.

Galerkin finite element approximation for semilinear stochastic time-tempered fractional wave equations with multiplicative white noise and fractional Gaussian noise

Then the space-time multiplicative white noise and fractional Gaussian noise are discretized, which results in a regularized stochastic fractional wave equation while introducing a modeling error in the mean-square sense. Expand abstract.

Cosmology in non-local Bopp-Podolski electrodynamics

However, independent of the parameters of the theory, the model predicts an isotropic universe at late times. Expand abstract.

Space-time multilevel Monte Carlo methods and their application to cardiac electrophysiology

This combination allows for space-time adaptivity, time-changing domains, and to take advantage of past samples to initialize the space-time solution. Expand abstract.
