A graceful labeling of a graphG = (V,E) assigns |V | distinct integers from the set {0, . . . , |E|} to the vertices of G so that the absolute values of their differences on the |E| edges of G constitute the set {1, . . . , |E|}. A graph is graceful if it admits a graceful labeling. The forty-year old Graceful Tree Conjecture, due to Ringel and Kotzig, states that every tree is graceful. We pro...

For an integer w, let Sw be the algebraic triangulated category generated by a w-spherical object. We determine the Picard group of Sw and show that each orbit category of Sw is triangulated and is triangle equivalent to a certain orbit category of the bounded derived category of a standard tube. Moreover, we describe the Ringel–Hall Lie algebra associated to Sw in the sense of Peng and Xiao.

Rabinow starts his search for new anthropological methods with the question of what the contemporary is. He identifies two meanings. The first is the ordinary English-language meaning: contemporary means that something occurs at the same period of time as something else. The issue is not when something happened, but that it happened at the same period of time. Cicero was the contemporary of Cae...
