    • Equations 1 and 2 are related by partial integration, subject only to the vanishing of a surface term. It is intuitively clear that there are many other forms for the local kinetic energy that also reduce to eq 1 by partial integration, but which have more complicated forms for the vanishing surface term

    • It seems exceedingly unlikely that the local total kinetic energy would have the Laplacian form for the exact exchange-correlation energy functional. However, as this functional is unknown in any useful explicit form, it seems impossible to prove this

    • This postulate is based on the incredible diversity of local kinetic energy forms that are attainable if f is allowed to be a functional of the wavefunction. This leads the authors to believe that virtually any well-behaved local kinetic energy function can be reverse-engineered to generate a quasiprobability distribution function
