MRS differentials conjecture

About 4 years old · traced to

Let y(h)y(h) be the spectrum under consideration, and let h2h+i−j,jh_{2h+i-j,j}, bh+i,jb_{h+i,j}, and qhq_h denote the classes and coefficient appearing in its localized Adams spectral sequence. MRS differentials conjecture. In the localized Adams spectral sequence for y(h)y(h), each class h2h+i−j,jh_{2h+i-j,j} survives to the (2pj)th(2p^j)^{\mathrm{th}} page, bh+i,jb_{h+i,j} survives to the (2ph−1+1)st(2p^{h-1}+1)^{\mathrm{st}} page, and there are differentials

d2pj(h2h+i−j,j)=qhbh+i,h−1−jpjd_{2p^j}(h_{2h+i-j,j})=q_h b_{h+i,h-1-j}^{p^j}

for each i>0i>0 and 0≤j≤h−10\leq j\leq h-1. This is the expected pattern of differentials truncating the polynomial generators on the localized Adams E2E_2-page; the source attributes it to MRS, and the subsequent collapse behavior is treated separately.
