Convergence of ground state solutions for nonlinear Schrödinger equations on graphs
Ning Zhang, Liang Zhao
We consider the nonlinear Schrödinger equation on a locally finite graph . We prove via the Nehari method that if satisfies certain assu…
Analysis on Cohort Effects in view of Differential Geometry and its Applications
Ning Zhang, Liang Zhao
This paper analyzes birth cohort effects and develops an approach which is based on differential geometry to identify and measure cohort effects in mortality data sets. The measure…
Existence of solutions for a higher order Kirchhoff type problem with exponential critical growth
Liang Zhao, Ning Zhang
The higher order Kirchhoff type equation $$\int_{\mathbb{R}^{2m}}(|\nabla^m u|^2 +\sum_{γ=0}^{m-1}a_γ(x)|\nabla^γu|^2)dx \left((-Δ)^m u+\sum_{γ=0}^{m-1}(-1)^γ\nabla^γ\cdot(a_γ(x)\n…
Mortality cohort effect detection and measurement based on differential geometry
Ning Zhang, Liang Zhao
This paper analyzes mortality cohort effect of birth year and develops an approach to identify and measure cohort effects in mortality data set. The approach is based on differenti…
