Differences between perfect powers: prime power gaps
Algebra & Number Theory, 2023 We develop machinery to explicitly determine, in many instances, when the difference $x^2-y^n$ is divisible only by powers of a given fixed prime. This combines a wide variety of techniques from Diophantine approximation (bounds for linear forms in logarithms, both archimedean and non-archimedean, lattice basis reduction, methods for solving Thue ...

On perfect powers in $k$-generalized Pell sequence
Mathematica Bohemica, 2022 Summary: Let \(k\geq 2\) and let \((P_{n}^{(k)})_{n\geq 2-k}\) be the \(k\)-generalized Pell sequence defined by \[P_{n}^{(k)}=2P_{n-1}^{(k)}+P_{n-2}^{(k)}+\cdots +P_{n-k}^{(k)}\] for \(n\geq 2\) with initial conditions \[P_{-(k-2)}^{(k)}=P_{-(k-3)}^{(k)}=\cdots =P_{-1}^{(k)}=P_{0}^{(k)}=0,P_{1}^{(k)}=1.\] In this study, we handle the equation \(P_{n}^{

Chapter 14. The Swedish perfect and periphrasis
, 2021 This paper investigates the apparent near-optionality of the perfect auxiliary ha (‘have’) in Swedish. Restrictions on the near-optionality of ha-omission are typically recognized in the previous literature as lexical or structural. The paper scrutinizes

IEEE Access, 2017 In this paper, we investigate the resource allocation problem for multi-user full-duplex deviceto-device (D2D) underlay communication, considering both perfect channel state information (CSI) and statistical CSI scenarios.

The cubic power graph of finite abelian groups
AKCE International Journal of Graphs and Combinatorics, 2021 Let G be a finite abelian group with identity 0. For an integer the additive power graph of G is the simple undirected graph with vertex set G in which two distinct vertices x and y are adjacent if and only if x + y = nt for some with When the additive ...

Low-Complexity Power Allocation in NOMA Systems With Imperfect SIC for Maximizing Weighted Sum-Rate
IEEE Access, 2019 In this paper, we investigate the power allocation for maximizing weighted sum rate (WSR) in downlink multiple carriers non-orthogonal multiple access (MC-NOMA) systems with imperfect successive interference cancellation (SIC).

A recursive construction for perfect hash families
Journal of Mathematical Cryptology, 2009 A known recursive construction for perfect hash families multiplies the number of factors by q, where q is the largest prime power not exceeding the number of symbols.
