f then induces
the zero function on some homomorphic images of
the polynomial ring R[x. For a prime _{1},...,x_{k}]p and a natural number
1≤n≤p, we characterize and count null polynomials
of order k over the ring Z. Moreover,
when _{pn}n≤p we count the polynomial functions and the polynomial permutations over a homomorphic image of
Z
that is isomorphic to
_{pn}[x_{1},...,x_{k}]Z.

Mahadi Ddamulira
(TU, advisor R. Tichy): On the x-coordinates of Pell equations which are k-generalized
Fibonacci numbers | |

k-generalized Fibonacci sequence which starts with 0,..,0,1
(k terms) and each term afterwards is the sum of the k preceding
terms. In this seminar, for an integer d≥2 which is square-free, we
show that there is at most one value of the positive integer x
participating in the Pell equation x which is a ^{2}-dy^{2}=
±1k-generalized Fibonacci number, with a
few exceptions that we completely
characterize. This paper extends previous work from Luca et. al 2017 for
the case k=2 and Luca et. al 2018 for the case k=3.
This is joint work with Florian Luca. | |
