Fundamental quantum QSAR (Q2SAR) equation: extensions, nonlinear terms, and generalizations within extended Hilbert–Sobolev spaces

AbstractThe fundamental quantum QSAR (Q2SAR) equation is analyzed from the point of view of the expectation value structure in extended Hilbert and Sobolev spaces. A new general Q2SAR picture emerges. © 2002 Wiley Periodicals, Inc. Int J Quantum Chem 88: 167–182, 2002
