Nilpotent pairs, dual pairs, and sheets [PDF]
Journal of Algebra, 240 (2001), 635-664, 1999 Recently, V.Ginzburg introduced the notion of a principal nilpotent pair (= pn-pair) in a semisimple Lie algebra {\frak g}. It is a double counterpart of the notion of a regular nilpotent element. A pair (e_1,e_2) of commuting nilpotent elements is called a pn-pair, if the dimension of their simultaneous centralizer is equal to the rank of {\frak g ...

Pairing Powers of Pythagorean Pairs [PDF]
arXivA pair $(a, b)$ of positive integers is a pythagorean pair if $a^2 + b^2$ is a square. A pythagorean pair $(a, b)$ is called a pythapotent pair of degree $h$ if there is another pythagorean pair $(k,l)$, which is not a multiple of $(a,b)$, such that $(a^hk, b^hl)$ is a pythagorean pair.

Mathematics of Computation, 2010 Isogeny volcanoes are graphs whose vertices are elliptic curves and whose edges are $\ell$-isogenies. Algorithms allowing to travel on these graphs were developed by Kohel in his thesis (1996) and later on, by Fouquet and Morain (2001). However, up to now, no method was known, to predict, before taking a step on the volcano, the direction of this step.

Weak-pairing higher order topological superconductors [PDF]
Physical review B, 2018 Conventional topological superconductors are fully gapped in the bulk but host gapless Majorana modes on their boundaries. We instead focus on a new class of superconductors, second-order topological superconductors, that have gapped, topological ...

Microfluidic Device for Droplet Pairing by Combining Droplet Railing and Floating Trap Arrays
Micromachines, 2021 Droplet microfluidics are characterized by the generation and manipulation of discrete volumes of solutions, generated with the use of immiscible phases. Those droplets can then be controlled, transported, analyzed or their content modified. In this wide

Why pair? Evidence of aggregative mating in a socially monogamous marine fish (Siganus doliatus, Siganidae) [PDF]
Royal Society Open Science, 2015 Many species live in stable pairs, usually to breed and raise offspring together, but this cannot be assumed. Establishing whether pairing is based on mating, or an alternative cooperative advantage, can be difficult, especially where species show no ...

Authenticated Key Exchange Protocol in the Standard Model under Weaker Assumptions
Cryptography, 2023 A two-party authenticated key exchange (AKE) protocol allows each of the two parties to share a common secret key over insecure channels, even in the presence of active adversaries who can actively control and modify the exchanged messages.
