A theoretical model is developed to visualize three‐dimensional refractive index profiles in transmission holographic gratings. In this work, it is applied to photopolymerizable hydrogels, enabling detailed analysis of the internal structure of recorded holograms and their evolution under different degradation conditions.

Existence and uniqueness of normalized solutions for the Kirchhoff equation
For a class of Kirchhoff functional, we first give a complete classification with respect to the exponent $p$ for its $L^2$-normalized critical points, and show that the minimizer of the functional, if exists, is unique up to translations. Secondly, we search for the mountain pass type critical point for the functional on the $L^2$-normalized manifold,

Stability and critical dimension for Kirchhoff systems in closed manifolds
The Kirchhoff equation was proposed in 1883 by Kirchhoff [Vorlesungen über Mechanik, Leipzig, Teubner, 1883] as an extension of the classical D’Alembert’s wave equation for the vibration of elastic strings. Almost one century later, Jacques Louis Lions [“

Asymptotic Limits for Mildly Degenerate Kirchhoff Equations [PDF]
We study the asymptotic behavior of the solutions of the mildly degenerate Kirchhoff equation with a dissipative term. We obtain a new estimate on second-in-time derivative of the solution. Moreover we renormalize the solution in such a way that the renormalization as a no zero limit as t goes to infinity.
