Abstract

We show that the strongest form of Hopkins’ chromatic splitting conjecture, as stated by Hovey, cannot hold at chromatic level n = 2 at the prime p = 2. More precisely, for V (0), the mod 2 Moore spectrum, we prove that πkL1LK(2)V (0) is not zero when k is congruent to 3 modulo 8. We explain how this contradicts the decomposition of L1LK(2)S predicted by the chromatic splitting conjecture.
