The present work extends our short communication [1]. For smooth marginally outer trapped surfaces (MOTS) in a smooth spacetime we define stability with respect to variations along arbitrary vectors v normal to the MOTS. After giving some introductory material about linear non self-adjoint elliptic operators, we introduce the stability operator Lv and we characterize stable MOTS in terms of sig...

Urban green space (UGS) is crucial in providing ecosystem services and optimizing the health of urban residents. This study aimed at identifying suitable sites for UGS development using geospatial techniques Addis Ababa City. In present study, an analytical hierarchical process with Geographic Information Systems based multi-criteria evaluation was used development. Eight parameters namely land...
