“…Zagreb indices are employing as molecular descriptors in QSPR and QSAR, see [11,12]. In the interdisplinary of mathemactics, chemistry and physics, it is not surprising that there are numerous studies of properties of the Zagreb indices of molecular graphs [13,14,15,16,17,18,19,20,21]. In [22,23], some bounds of (chemical) trees on Zagreb indices are studied and surveyed.…”
