AbstractWe classify the ranks of positive semidefinite completions of Hermitian band matrices and other partially specified Hermitian matrices with chordal graphs and specified main diagonals. Completing a partially specified matrix means filling in the unspecified entries
The Gram dimension gd(G) of a graph G is the smallest inte- ger k ≥ 1 such that any partial real sym...
