Constraining $f(R)$ Theories with Temporal Variation of Fine Structure Constant [PDF]

, 2010
It is well-known that $f(R)$ theories in Einstein frame is conformally equivalent to quintessence models in which the scalar field minimally couples with gravity. If there exists a matter system in Jordan frame, then it interacts with the scalar field in

Hochster duality in derived categories and point-free reconstruction of schemes [PDF]

, 2015
For a commutative ring $R$, we exploit localization techniques and point-free topology to give an explicit realization of both the Zariski frame of $R$ (the frame of radical ideals in $R$) and its Hochster dual frame, as lattices in the poset of ...
