Kirchhoff equations with indefinite potentials

Applicable Analysis, 2021
In this paper we consider four-superlinear Kirchhoff equations. In contrast to most studies, we allowed the potential V is indefinite, precisely, the operator −Δ+V possesses a finite-dimensional ne...

Mouse embryonic stem cells exhibit indefinite proliferative potential

Journal of Cellular Physiology, 1987
AbstractThe proliferative potential of embryonic stem cells was examined. In contrast to the current concept of the finite life‐span being the hallmark of normal cells, we have been able to maintain these embryonic stem cells in vitro up to about 250 cumulative doublings with no indication of “crisis” or transformation.
