Blowup solutions and their blowup rates for parabolic equations with non-standard growth conditions
Electronic Journal of Qualitative Theory of Differential Equations, 2011 This paper concerns classical solutions for homogeneous Dirichlet problem of parabolic equations coupled via exponential sources involving variable exponents. We first establish blowup criteria for positive solutions.

A NON-RADIALLY SYMMETRIC SOLUTION TO A CLASS OF ELLIPTIC EQUATION WITH KIRCHHOFF TERM
Journal of Applied Analysis & Computation, 2019 Summary: We consider the following equation with Kirchhoff term \(-(a+b\int_{\mathbb{R}^3} |\nabla u|^2 dx) \Delta u + u =|u|^{p-2}u, u \in H^1 (\mathbb{R}^3)\), where \(a, b\) are positive constants and \(2 < p < 6\). By deducing a variant variational identity and a constraint set, we are able to prove the existence of a non-radially symmetric ...

Analysis of Bingham fluid radial flow in smooth fractures
Journal of Rock Mechanics and Geotechnical Engineering, 2020 Solutions for radial flow of a Bingham fluid are analyzed in this paper. It aims to eliminate confusions in the literature concerning the plug flow region in different solutions for analysis and design of grouting in rock fractures. The analyses based on

Non-radial solutions to a bi-harmonic equation with negative exponent [PDF]
Calculus of Variations and Partial Differential Equations, 2019 We prove the existence of non-radial entire solution to $$Δ^2 u+u^{-q}=0\quad\text{in }\mathbb{R}^3,\quad u>0,$$ for $q>1$. This answers an open question raised by P. J. McKenna and W. Reichel (E. J. D. E. \textbf{37} (2003) 1-13).

European Physical Journal C: Particles and Fields, 2022 Complex scalars in U(1)-symmetric potentials can form stable Q-balls, non-topological solitons that correspond to spherical bound-state solutions. If the U(1) charge of the Q-ball is large enough, it can support a tower of unstable radial excitations ...

Multiple non-radial solutions for coupled Schrödinger equations
Journal of Differential EquationsThe paper deals with the existence of non-radial solutions for an $N$-coupled nonlinear elliptic system. In the repulsive regime with some structure conditions on the coupling and for each symmetric subspace of rotation symmetry, we prove the existence of an infinite sequence of non-radial positive solutions and an infinite sequence of non-radial nodal
