On a measure of noncompactness in the space of continuous functions

1991
For a bounded subset \(X\) of \(C[0,1]\) define \[ \omega_ 0(X)=\lim_{h\to 0} \sup_{x\in X} \sup\{| x(t)-x(s)|:\;| t-s|\leq h;\;t,s\in [0,1]\} \] and \[ p(X)=\sup_{t_ 0\in[0,1]} \lim_{h\to 0} \sup_{x\in X} \sup\{| x(t)-x(t_ 0)|:\;| t-t_ 0|\leq h;\;t\in[0,1]\}.
