Homework Statement
let V be a vector space and S be a subset of V with the following property
for all v in V, there exist some positive integer p such that v/p is in S
given: S is closed and S has the property as described above. prove interior of S is NOT empty
Homework Equations
The Attempt at a Solution
since S is closed, we can define other closed sets S1, S2... such that the int(Sn)=0 and int(S U S1 U S2 U...)=/=0. once we have this we can apply baire's theorem.
problem is how do i define S1, S2,...
