For diagonal cubic surfaces, we give an upper bound for E. Peyre’s Tamagawa type number in terms of the coefficients of the defining equation.

Conceptual modeling is the defining characteristic of object-orientation and provides a unifying perspective and a pedagogical approach focusing upon the modelling aspects of object-orientation. Reinforcing conceptual modelling as a basis for CS1 provides an appealing course structure based on core elements from a conceptual framework for object-orientation as well as a systematic approach to p...

The characterization or subsequent use of a propagating optical quantum state requires the knowledge of its precise temporal mode. Defining this mode structure very often relies on a detailed a priori knowledge of the used resources, when available, and can additionally call for an involved theoretical modeling. In contrast, here we report on a practical method enabling us to infer the optimal ...
