Abstract: We establish sufficient conditions for a C c 1 $$ {C}_c^1 $$ -local diffeomorphism between Fréchet spaces to be a global diffeomorphism. We extend Clarke’s theory of generalized gradients to more general Fréchet spaces. As… read more here.

DOI: 10.1080/02723638.2020.1745517
Abstract: ABSTRACT In a world where rapid urban expansion is occurring in peri-urban fringes of the Global South, this paper advocates for a foregrounding of urban-rural fringes as sites of urban theorization. Heeding to postcolonial urbanism's… read more here.
