<p>In</p> <p><a href="http://arxiv.org/PS_cache/hep-th/pdf/9302/9302103v1.pdf" rel="nofollow">http://arxiv.org/PS_cache/hep-th/pdf/9302/9302103v1.pdf</a></p> <p>physicists calculate (predict) genus one GW invariants of quintic (Table 1) and some other cases (Table 2).</p> <p>Can any body explain to me (mathematically) how do they do that? What is the B-model object (integral) which they consider and extract these numbers from (conjecturally via some mirror relation) ?</p> <p>Please at least try to explain mathematically.</p>
