On maximal curves that are not quotients of the Hermitian curve [PDF]

open access: yesFinite Fields and Their Applications, 2015
For each prime power ź the plane curve X ź with equation Y ź 2 - ź + 1 = X ź 2 - X is maximal over F ź 6 . Garcia and Stichtenoth in 2006 proved that X 3 is not Galois covered by the Hermitian curve and raised the same question for X ź with ź 3 ; in this

Curves covered by the Hermitian curve [PDF]

open access: yesFinite Fields and Their Applications, 1998
A family of maximal curves is investigated that are all quotients of the Hermitian curve. These curves provide examples of curves with the same genus, the same automorphism group and the same Weierstrass semigroup at a generic point, but that are not ...

Intersection of irreducible curves and the Hermitian curve [PDF]

open access: yesJournal of Algebra
Let $\mathcal{H}_q$ denote the Hermitian curve in $\mathbb{P}^2$ over $\mathbb{F}_{q^2}$ and $\mathcal{C}_d$ be an irreducible plane projective curve in $\mathbb{P}^2$ also defined over $\mathbb{F}_{q^2}$ of degree $d$.

Some Ree and Suzuki curves are not Galois covered by the Hermitian curve [PDF]

open access: yesFinite Fields and Their Applications, 2016
The Deligne-Lusztig curves associated to the algebraic groups of type $^2A_2$, $^2B_2$, and $^2G_2$ are classical examples of maximal curves over finite fields. The Hermitian curve $\mathcal H_q$ is maximal over $\mathbb F_{q^2}$, for any prime power $q$,

On nested code pairs from the Hermitian curve [PDF]

open access: yesFinite Fields and Their Applications, 2018
Nested code pairs play a crucial role in the construction of ramp secret sharing schemes [16] and in the CSS construction of quantum codes [15]. The important parameters are (1) the codimension, (2) the relative minimum distance of the codes, and (3) the

On the spectrum of sizes of semiovals contained in the Hermitian curve [PDF]

open access: yesEuropean Journal of Combinatorics, 2015
Some constructions and bounds on the sizes of semiovals contained in the Hermitian curve are given. A construction of an infinite family of 2 -blocking sets of the Hermitian curve is also presented.

On the Hermitian curve and its intersections with some conics [PDF]

open access: yesFinite Fields and Their Applications, 2014
We classify completely the intersections of the Hermitian curve with parabolas in the affine plane. To obtain our results we employ well-known algebraic methods for finite fields and geometric properties of the curve automorphisms.

On the automorphism group of a family of maximal curves not covered by the Hermitian curve

open access: yesFinite Fields and Their Applications
In this paper we compute the automorphism group of the curves $\mathcal{X}_{a,b,n,s}$ and $\mathcal{Y}_{n,s}$ introduced in Tafazolian et al. in 2016 as new examples of maximal curves which cannot be covered by the Hermitian curve. They arise as subcovers of the first generalized GK curve (GGS curve). As a result, a new characterization of the GK curve,

Gravity induced spontaneous radiation

open access: yesNuclear Physics B, 2023
We suggest that behind the black hole information paradox is a new and universal radiation mechanism, Gravity Induced Spontaneous Radiation, or GISR hereafter.

ON PSEUDO-HERMITIAN MAGNETIC CURVES IN SASAKIAN MANIFOLDS [PDF]

open access: yesFacta Universitatis, Series: Mathematics and Informatics, 2021
We define pseudo-Hermitian magnetic curves in Sasakian manifolds endowed with the Tanaka-Webster connection. After we give a complete classification theorem, we construct parametrizations of pseudo-Hermitian magnetic curves in $\mathbb{R}^{2n+1}(-3)$.
