Let V be a complete Hausdorff locally convex topological vector space over the field mathbbK.
Let B be a subset of V satisfying
.
Linearly Independent: For all functions f in mathbbKB, if displaystylesumbinBf(b)cdotb=0, then f is identically zero.
Spanning Set: For all vectors v in V, there exists a function f in mathbbKB such that displaystylesumbinBf(b)cdotb=v.
.
Let C be another subset of V satisfying the above conditions with B replaced with C.
Does it follow that |B|=|C|?
.
(I know such 'bases' don't always exist, but when they do, do they give a unique dimension?)
