,The diophantine equation x3 − y2 = r,with good reduction outside SS., where S. is some set of prime divisors of 2 or 3 in ., satisfy certain additional conditions (see Corollaries 2.10 and 2.11, see also 2.12) and hence for the construction of these curves the above equation need not be solved completely. In the present chapter we deal now with the construction of the set B..

In these notes we deal with the following .: How can one explicitly construct a set of representatives for the isogeny classes of elli

For that we had to assume that every prime divisor of 2 or 3 is contained in S. Solutions in B. that give rise to elliptic curves

Variation in female mate choice within guppy populations: Population divergence, multiple ornamentsview recent work on variation within and among guppy (.) populations in female mate choice and mating preferences. Empirical results demonstrate that there is substantial variation within and among populations in female responsiveness and choosiness, and much of this variation is genetic. Evidence f
