The Betti numbers of the moduli space of stable sheaves of rank 3 on P2 [PDF]
, 2011 This article computes the generating functions of the Betti numbers of the moduli space of stable sheaves of rank 3 on the projective plane P2 and its blow-up. Wall-crossing is used to obtain the Betti numbers on the blow-up.

Similarity stabilizes blow up [PDF]
Journal of Differential Equations, 1999 The blow-up of solutions to a quasilinear heat equation is studied using a similarity transformation that turns the equation into a nonlocal equation whose steady solutions are stable. This allows energy methods to be used, instead of the comparison principles used previously.

Blow-up analysis in a quasilinear parabolic system coupled via nonlinear boundary flux
Electronic Journal of Qualitative Theory of Differential Equations, 2021 This paper deals with the blow-up of the solution for a system of evolution $p$-Laplacian equations $u_{it}=\text{div}(|\nabla u_{i}|^{p-2}\nabla u_{i})\;(i=1,2,\dots,k)$ with nonlinear boundary flux.

Shadows of blow-up algebras [PDF]
, 2002 We study different notions of blow-up of a scheme X along a subscheme Y, depending on the datum of an embedding of X into an ambient scheme. The two extremes in this theory are the ordinary blow-up, corresponding to the identity, and the `quasi-symmetric

Field patterns without blow up
New Journal of Physics, 2017 Field patterns, first proposed by the authors in Milton and Mattei (2017 Proc. R. Soc. A 473 20160819), are a new type of wave propagating along orderly patterns of characteristic lines which arise in specific space-time microstructures whose geometry in

Stable self-similar blow-up dynamics for slightly $L^2$-supercritical generalized KdV equations [PDF]
, 2015 In this paper we consider the slightly $L^2$-supercritical gKdV equations $\partial_t u+(u_{xx}+u|u|^{p-1})_x=0$, with the nonlinearity ...

Blow up profiles for a quasilinear reaction-diffusion equation with weighted reaction
, 2019 We perform a thorough study of the blow up profiles associated to the following second order reaction-diffusion equation with non-homogeneous reaction: $$ \partial_tu=\partial_{xx}(u^m) + |x|^{\sigma}u^p, $$ in the range of exponents $10$.
