Symbol y_ij

The passage around this formula

…used. Define the dimensionless node potential $\phi(\mathbf x)$ := $\ln$ U($\mathbf x$) and the edge observable actually recorded between linked clocks i and j , $y_{ij} := \ln(\nu_j/\nu_i) = \phi(\mathbf x_i) - \phi(\mathbf x_j)$. At weak field this reduces to the familiar $y_{ij}$ $\approx$ ($\Phi_i$ - $\Phi_j$)/$c^2$ for Newtonian potential $\Phi$ , exactly the quantity real fibre-linked clock comparisons already report [ 1 , 7 ] . Collect every measured edge into a vector y , one entry per link, and encode the network’s topology in an incidence matrix B : row e = (i,j) has a…
