From Caristi's Theorem to Ekeland's Variational Principle in 0[sigma] -Complete Metric-Like Spaces

We discuss the extension of some fundamental results in nonlinear analysis to the setting of [subscript]0σ[/subscript] -complete metric-like spaces. Then, we show that these extensions can be obtained via the corresponding results in standard metric spaces.
