Pgl2(FL) Number Fields With Rational Companion Forms, David P. Roberts
Pgl2(FL) Number Fields With Rational Companion Forms, David P. Roberts
Mathematics Publications
We give a list of PGL2(Fl) number fields for ℓ ≥ 11 which have rational companion forms. Our list has fifty-three fields and seems likely to be complete. Some of the fields on our list are very lightly ramified for their Galois group.
Some Conjectures Concerning Triangular Numbers, Bruce Brandt
Some Conjectures Concerning Triangular Numbers, Bruce Brandt
Journal of the Minnesota Academy of Science
Strong empirical evidence supports conjectures that certain number patterns always hold. These patterns concern the function cr, defined by the equation cr(n) = n - m2, m2 being the nearest square to n, on the domain of the triangular numbers. Triangular squares or triangular numbers of the form m2+m are also mentioned in most of the conjectures. One of the conjectures, for example, is that the sum of cr over the triangular numbers up to a triangular square is 0. Some of these patterns can be described by strings of symbols, such as "S" and "L," formed by first writing …

In a previous paper (1), I stated many conjectures about triangular numbers. Since submitting that paper I have discovered many more results, including generalizations, which are presented here.
