Lubin-Tate formal groups and module structure over Hopf orders

Werner Bley, Robert Boltje (1999)

Journal de théorie des nombres de Bordeaux

Over the last years Hopf orders have played an important role in the study of integral module structures arising in arithmetic geometry in various situations. We axiomatize these situations and discuss the properties of the (integral) Hopf algebra structures which are of interest in this general setting. In particular, we emphasize the role of resolvents for explicit computations. As an illustration we apply our results to determine the Hopf module structure of the ring of integers in relative Lubin-Tate...

Lucas balancing numbers

Kálmán Liptai (2006)

Acta Mathematica Universitatis Ostraviensis

A positive n is called a balancing number if 1 + 2 + + ( n - 1 ) = ( n + 1 ) + ( n + 2 ) + + ( n + r ) . We prove that there is no balancing number which is a term of the Lucas sequence.

Lucas factoriangular numbers

We show that the only Lucas numbers which are factoriangular are 1 and 2 .

Lucas sequences and repdigits

Hayder Raheem Hashim, Szabolcs Tengely (2022)

Mathematica Bohemica

Let ( G n ) n 1 be a binary linear recurrence sequence that is represented by the Lucas sequences of the first and second kind, which are { U n } and { V n } , respectively. We show that the Diophantine equation G n = B · ( g l m - 1 ) / ( g l - 1 ) has only finitely many solutions in n , m + , where g 2 , l is even and 1 B g l - 1 . Furthermore, these solutions can be effectively determined by reducing such equation to biquadratic elliptic curves. Then, by a result of Baker (and its best improvement due to Hajdu and Herendi) related to the bounds of the integral points on...
