Buildings of types Cn and Dn are defined by rank n polar spaces. The associated building Grassmannians are polar and half-spin Grassmannians. Apartments in dual polar spaces and half-spin Grassmannians were characterized in [4]. We characterize apartments in all polar Grassmannians consisting of non-maximal singular subspaces. This characterization is a partial case of more general results conc...

By integrating organizational learning theory with the family firm literature, we seek to enhance our understanding of radical innovation in (multi)family-owned firms. We theorize that goal diversity and path dependency multifamily ownership creates negatively affects positive relationship between knowledge integration innovation. However, this is not case for multifamily-owned firms which memb...
