Thetanullwerte: From periods to good equations

Thetanullwerte: from Periods to Good Equations

We will show the utility of the classical Jacobi Thetanullwerte for the description of certain period lattices of elliptic curves, providing equations with good arithmetical properties. These equations will be the starting point for the construction of families of elliptic curves with everywhere good reduction.

Interrupting long periods of sitting: good STUFF

There is increasing evidence that sedentary behaviour is in itself a health risk, regardless of the daily amount of moderate to vigorous physical activity. Therefore, sedentary behaviour should be targeted as important health behaviour. It is known that even relatively small changes of health behaviour often require serious efforts from an individual and from people in their environment to beco...

Generalized class invariants with ’Thetanullwerte’

We introduce generalized class invariants as quotients of Thetanullwerte, which realize the computation of class polynomials more efficiently than as quotients of values of the Dedekind η−function. Furthermore, we prove that these invariants are units in the corresponding class field as most of their classical counterparts. keywords: class polynomials, theta functions, complex multiplication

Why and How Is Compassion Necessary to Provide Good Healthcare? Comments From an Academic Physician; Comment on “Why and How Is Compassion Necessary to Provide Good Quality Healthcare?”

This is a short commentary to the editorial issued by Marianna Fotaki, entitled: “Why and how is compassion necessary to provide good quality healthcare.” It introduces the necessity of a more cognitive approach to explore further the determinants of behavior towards compassionate care. It raises questions about the importance of training towards a more patient-care and values driven healthcare...
