Question
(b) Let V be the F-vector space of F-valued sequences (a,)n20. For each i > 0, let &; be the sequence
whose i-th term is 1, and whose other terms are 0. Show that the set 6o, d1, ... , 8n, ... does not span V,
by giving an explicit description of the span of this set.
Remark: A general principle of logic known as Zorn's implies that every vector space has a basis. But no
one has ever been (nor will ever be) able to write down an explicit basis for the vector space V of (b).
