A cone conjecture for log Calabi-Yau surfaces by Jennifer Li

“…We prove that (1) the action of the automorphism group of $(Y_e,D_e)$ on its nef effective cone admits a rational polyhedral fundamental domain; and (2) the action of the monodromy group on the nef effective cone of a very general surface in the deformation type admits a rational polyhedral fundamental domain. …”

Yorùbá Philosophy and Contemporary Nigerian Realities by Adeshina Afolayan

“…Specifically, it is grounded on the urgency of interrogating Nigeria’s postcolonial realities in the light of Yorùbá philosophical insights that, among other things, enable a rethinking of postcolonial social practices especially as sites of identity, agency, knowledge, objectivity, and even of resistance and power. Premised on the fundamental assumption that Yorùbá philosophy constitutes a fundamental site of scholarship within which the task of understanding and reinventing the Nigerian state and societies can be achieved, the Introduction weaves this assumption into the analysis of the fourteen essays that explores Nigeria’s postcolonial realities ranging from overpopulation, public (im)morality, ethnic conflict, injustice, and democratic deficit to environmental degradation, disability, depersonalization, youth culture, and a glaring disconnection between educational theory and practice. …”
