Journal 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 $$ \mathcal{N} $$

Refined Regularity of the Blow-Up Set Linked to Refined Asymptotic Behavior for the Semilinear Heat Equation [PDF]
Advanced Nonlinear Studies, 2017 We consider u(x,t)${u(x,t)}$, a solution of ∂tu=Δu+|u|p-1u${\partial_{t}u=\Delta u+|u|^{p-1}u}$ 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}$.

A SURVEY ON THE BLOW UP TECHNIQUE [PDF]
International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2011 The blow up technique is widely used in desingularization of degenerate singular points of planar vector fields. In this survey, we give an overview of the different types of blow up and we illustrate them with many examples for better understanding. Moreover, we introduce a new generalization of the classical blow up.

Nonlinear Analysis, 2020 In this paper, we establish the results of nonexistence and existence of blow-up radial solutions for a k-Hessian equation with a nonlinear operator. Under some suitable growth conditions for nonlinearity, the result of nonexistence of blow-up solutions ...

Asymptotic Self-Similar Blow-Up Profile for Three-Dimensional Axisymmetric Euler Equations Using Neural Networks. [PDF]
Physical Review Letters, 2022 Whether there exist finite-time blow-up solutions for the 2D Boussinesq and the 3D Euler equations are of fundamental importance to the field of fluid mechanics.

Global existence and infinite time blow-up of classical solutions to chemotaxis systems of local sensing in higher dimensions [PDF]
Nonlinear Analysis, 2021 This paper deals with the fully parabolic chemotaxis system of local sensing in higher dimensions. Despite the striking similarity between this system and the Keller–Segel system, we prove the absence of finite-time blow-up phenomenon in this system even

Delayed blow-up by transport noise [PDF]
Communications 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]
Journal 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
