Convergence of exterior solutions to radial Cauchy solutions for $\partial_t^2U-c^2\Delta U=0$
Electronic Journal of Differential Equations, 2016 Consider the Cauchy problem for the 3-D linear wave equation $\partial_t^2U-c^2\Delta U=0$ with radial initial data $U(0,x)=\Phi(x)=\varphi(|x|)$, $U_t(0,x)=\Psi(x)=\psi(|x|)$. A standard result states that $U$ belongs to $C([0,T];H^s(\mathbb{R}^3))$

Genetic programming approaches for solving elliptic partial differential equations
, 2008 In this paper, we propose a technique based on genetic programming (GP) for meshfree solution of elliptic partial differential equations. We employ the least-squares collocation principle to define an appropriate objective function, which is optimized ...

Existence of positive radial solutions for quasilinear elliptic equations and systems
Electronic Journal of Differential Equations, 2016 Under simple conditions on f and g, we show that existence of positive radial solutions for the quasilinear elliptic equation $$ \hbox{div}(\phi_1(|\nabla u|) \nabla u)=a(|x|)f(u) \quad x\in \mathbb{R}^N, $$ and for the system $$\displaylines{

FEBS Open Bio, EarlyView.Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Existence of positive radial solutions of general quasilinear elliptic systems
Advances in Nonlinear AnalysisLet Ω⊂Rn(n≥2)\Omega \subset {{\mathbb{R}}}^{n}\hspace{0.33em}\left(n\ge 2) be either an open ball BR{B}_{R} centred at the origin or the whole space. We study the existence of positive, radial solutions of quasilinear elliptic systems of the form Δpu=f1(∣
