The Wave Equation with Energy Dependent Potential - the Linear Case [PDF]

open access: yesمجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2011
We summarize recent works devoted to energy dependent potentials. It concerns the class of potentials having a coupling constant depending linearly on the energy. Introduced in the Schrödinger equation, it produces non-linear effects.

An Improved Approach to Wave Energy Resource Characterization for Sea States with Multiple Wave Systems

open access: yesJournal of Marine Science and Engineering, 2022
Generally, wave energy resource assessment and characterization are performed based on an entire wave spectrum, ignoring the detailed energy features that belong to wave systems, i.e., wind waves and swells. In reality, the energy is separately possessed

Geometric renormalization of large energy wave maps [PDF]

open access: yes, 2004
There has been much progress in recent years in understanding the existence problem for wave maps with small critical Sobolev norm (in particular for two-dimensional wave maps with small energy); a key aspect in that theory has been a renormalization ...
