Refined Regularity of the Blow-Up Set Linked to Refined Asymptotic Behavior for the Semilinear Heat Equation [PDF]

open access: yesAdvanced Nonlinear Studies, 2017
We consider u⁢(x,t)${u(x,t)}$, a solution of ∂t⁡u=Δ⁢u+|u|p-1⁢u${\partial_{t}u=\Delta u+|u|^{p-1}u}$ which blows up at some time T>0${T>0}$, where u:ℝN×[0,T)→ℝ${u:\mathbb{R}^{N}\times[0,T)\to\mathbb{R}}$, p>1${p>1}$ and (N-2)⁢p0}$.

Blow-up: A Free Lunch? [PDF]

open access: yesi-Perception, 2012
We consider operations that change the size of images, either shrinks or blow-ups . Image processing offers numerous possibilities, put at everyone's disposal with such computer programs as Adobe Photoshop.

Instantons from blow-up [PDF]

open access: yesJournal of High Energy Physics, 2019
We generalize Nakajima-Yoshioka blowup equations to arbitrary gauge group with hypermultiplets in arbitrary representations. Using our blowup equations, we compute the instanton partition functions for 4d N $$ \mathcal{N} $$ = 2 and 5d N $$ \mathcal{N} $$

Delayed blow-up by transport noise [PDF]

open access: yesCommunications in Partial Differential Equations, 2020
For some deterministic nonlinear PDEs on the torus whose solutions may blow up in finite time, we show that, under suitable conditions on the nonlinear term, the blow-up is delayed by multiplicative noise of transport type in a certain scaling limit. The

Delayed blow‐up for chemotaxis models with local sensing [PDF]

open access: yesJournal of the London Mathematical Society, 2020
The aim of this paper is to analyze a model for chemotaxis based on a local sensing mechanism instead of the gradient sensing mechanism used in the celebrated minimal Keller–Segel model. The model we study has the same entropy as the minimal Keller–Segel

On the numerical solutions for a parabolic system with blow-up

open access: yesAIMS Mathematics, 2021
We study the finite difference approximation for axisymmetric solutions of a parabolic system with blow-up. A scheme with adaptive temporal increments is commonly used to compute an approximate blow-up time.

Regression to the tail: Why the Olympics blow up [PDF]

open access: yesEnvironment and Planning, 2020
The Olympic Games are the largest, highest-profile, and most expensive megaevent hosted by cities and nations. Average sports-related costs of hosting are $12.0 billion. Non-sports-related costs are typically several times that. Every Olympics since 1960

Blow-up results of the positive solution for a class of degenerate parabolic equations

open access: yesOpen Mathematics, 2021
This paper is devoted to discussing the blow-up problem of the positive solution of the following degenerate parabolic equations: (r(u))t=div(∣∇u∣p∇u)+f(x,t,u,∣∇u∣2),(x,t)∈D×(0,T∗),∂u∂ν+σu=0,(x,t)∈∂D×(0,T∗),u(x,0)=u0(x),x∈D¯.\left\{\begin{array}{ll}{(r ...
