I will appreciate any help.
Consider the following function:
g ( x ) = { 1 x , if   x ( 1 , ) 0 , if   x ( , 1 ]
Determine the set { p [ 0 , ] : g L p ( λ ) }. I know that the set is equal to ( 1 , ] . But I am not sure how to calculate the cases p = 0 and p = .
In my textbook we have the following definitions for p = 0 and p = :
L ( μ ) = { f M ( E ) : R > 0 : | f | R     μ -almost everywhere }
and
L 0 ( μ ) = { f M ( E ) : lim t μ ( { | f | t } ) = 0 }
where M ( E ) = { f : X R : f     is   E - B ( R ) - measurable }.

Hints:
| g ( x ) | 1
| 1 / x | t | x | < 1 / t ... what is the size of the set { x ( 1 , ) : | x | < 1 / t } ?
