Razvan Gabriel Iagar, Ariel Sánchez
The large time behavior of solutions to the following generalized Burgers-Fisher-KPP equation w…
Blow-up rates and sets for a quasilinear diffusion equation with weighted source
Raúl Ferreira, Razvan Gabriel Iagar, Ariel Sánchez
Blow-up rates are established for general solutions to the quasilinear diffusion equation in the range of…
Euclid: The linear-construction covariance and cosmology
V. Lindholm, E. Sihvola, J. Valiviita +137
We study the properties of galaxy cluster 2-point correlation function covariance matrices estimated using the linear-construction (LC) method, which is computationally up to 20 ti…
Global self-similar solutions for Hardy-Hénon equations with linear and quasilinear diffusion
Razvan Gabriel Iagar, Ariel Sánchez, Erik Sarrion-Pedralva
Global self-similar solutions to the parabolic Hardy-Hénon equation are classified in the range of exponents…
CNN+FoF: application of deep learning to the identification of dark matter haloes
Soumadeep Maiti, Carlos M. Correa, Andrea Fiorilli +4
We present a deep-learning-based approach for identifying dark matter haloes in cosmological N-body simulations. Our framework consists of a volumetric Convolutional Neural Network…
Self-similar blow-up solutions for the supercritical parabolic Hardy-Hénon equation
Razvan Gabriel Iagar, Ana I. Muñoz, Ariel Sánchez
We classify the self-similar solutions presenting finite time blow-up to the parabolic Hardy-Hénon equation $$ \partial_tu=Îu+|x|^Ïu^p, \quad (x,t)\in\mathbb{R}^N\times(0,\infty…
