Blow up of solutions to semilinear wave equations
Electronic Journal of Differential Equations, 2003 This work shows the absence of global solutions to the equation $$ u_{tt} = Delta u + p^{-k}|u|^m, $$ in the Minkowski space $mathbb{M}_0=mathbb{R}imesmathbb{R}^N$, where $ m > 1$, $(N-1)m < N+1$, and $p $ is a conformal factor approaching 0 at infinity.

Environmental Control of Ferroelectricity in Hafnia Films
Advanced Materials, EarlyView.A reversible transition from nonferroelectric to ferroelectric behavior is achieved in hafnia films by modulating the surrounding atmosphere. The domain relaxation dynamics exhibit high sensitivity to environmental factors, including gas composition (ambient, N2, CO2, O2) and relative humidity, highlighting the crucial role of the measurement ...

Concentration of blow-up solutions for the Gross-Pitaveskii equation
Advances in Nonlinear AnalysisWe consider the blow-up solutions for the Gross-Pitaveskii equation modeling the attractive Boes-Einstein condensate. First, a new variational characteristic is established by computing the best constant of a generalized Gagliardo-Nirenberg inequality ...

Proceedings of the Edinburgh Mathematical Society, 2013 AbstractWe study a notion of ‘b-stability’, introduced previously by the author in connection with the existence of constant scalar curvature Kähler, and Kähler-Einstein, metrics. The main result is Theorem 1.2, which makes progress towards a statement that the existence of such metrics implies b-stability. The proof is a modification of an argument of
