Localized Energy Estimates for Strongly Indefinite Functionals
摘要
In this chapter we will prove some abstract results on the energy inequalities of strongly indefinite functionals on a Hilbert space E, whose norm and scalar product will be denoted, respectively, by \(\|\cdot \|\) and \(\left \langle \cdot ,\cdot \right \rangle \) . We anticipate that most of the results we will discuss could be carried out in a Banach spaces.
