Monomial-form conjecture for the vectors q(j)q(j)

Let r=s+pt(p1)dr=s+p^t(p-1)d, with pmiddp mid d, s=b+c(p1)s=b+c(p-1), and suppose that 2bp2\leq b\leq p and 1cp11\leq c\leq p-1. Fix apa_p such that 1<ν(ap)<p11<\nu(a_p)<p-1, and let t>ν(ap)+ct>\nu(a_p)+c. Suppose also that s>2ν(ap)s>2\nu(a_p), 1mmin{ν,c1ϵ}1\leq m\leq \operatorname{min}\{\nu,c-1-\epsilon\}, and (m,ν)(ν,ν(ap))(m,\nu)\neq(\nu,\nu(a_p)). Monomial-form conjecture. The monomials q(j)q(j) belong to Vr(m+1)+Ker(P)V_r^{(m+1)}+\operatorname{Ker}(P) for every cmjc1c-m\leq j\leq c-1. This is presented as a consequence of the matrix-form conjecture and would provide the required vanishing of these monomials in the quotient used to study the local constancy of the associated mod pp Galois representations; no resolution is given in the supplied text.
