A Generalized Diagonal Wythoff Nim

open access: yes, 2012
The P-positions of the 2-pile take-away game of Wythoff Nim lie on two beams of slope (sqrt(5)+1)/2 and (sqrt(5)−1)/2 respectively. We study extensions to this game where a player may also remove simultaneously pt tokens from either of the piles and qt ...

Coded Modulation Based On Rings Of Integers Modulo-q Part 2: Convolutional Codes

open access: yes, 2015
The authors aim to present a coded modulation method based on multilevel convolutional codes defined over finite rings of integers. A previously developed theory is applied to multi-level convolutional codes.

Quantum integers and cyclotomy

open access: yes, 2008
. A sequence of functions F = {fn(q)} ∞ n=1 satisfies the functional equation for multiplication of quantum integers if fmn(q) = fm(q)fn(qm) for all positive integers m and n.

The q-ary Gilbert-Varshamov bound can be improved for all but finitely many positive integers q [PDF]

open access: yes
For any positive integer $q\geq 2$ and any real number $\delta\in(0,1)$, let $\alpha_q(n,\delta n)$ denote the maximum size of a subset of $\mathbb{Z}_q^n$ with minimum Hamming distance at least $\delta n$, where $\mathbb{Z}_q=\{0,1,\dotsc,q-1\}$ and $n ...

q-Pascal Triangle

open access: yes, 2013
The q-binomial coefficients (n m)q are integers for integers q and 0≤m≤n. They satisfy the two recurrence equations: (n m)q=q^(n-m).(n-1 m-1)q + (n-1 m)q, (n m)q=q^(m).(n-1 m)q + (n-1 m-1)qEducação Superior::Ciências Exatas e da Terra ...

Projective modules of group rings over quadratic number fields [PDF]

open access: yes, 1994
Let K be a quadratic number field, Ok its ring of integers, and G a cyclic group of order prime p. In this thesis, we study the kernel group D(O(_K)G) and obtain a number of results concerning its order and structure. For K imaginary, we also investigate
