G\^ ateaux and Hadamard differentiability via directional differentiability

Ludek Zajicek

Let $X$ be a separable Banach space, $Y$ a Banach space and $f : X \to Y$ an arbitrary mapping. Then the following implication holds at each point $x \in X$ except a $σ$ -directional…

Hadamard differentiability via G\^ ateaux differentiability

Ludek Zajicek

Let $X$ be a separable Banach space, $Y$ a Banach space and $f : X \to Y$ a mapping. We prove that there exists a $σ$ -directionally porous set $A \subset X$ such that if $x\in X \set…
