15 صفحه اولGroup-arcs of Prime Power Order on Cubic Curves
This article continues the characterization of elliptic curves among sets in a finite plane which are met by lines in at most three points. The case treated here is that of sets of prime-power cardinality. 1 Notation GF (q) the finite field of q elements PG(2, q) the projective plane over GF (q) PG(1)(2, q) the set of lines in PG(2, q) P(X) the point of PG(2, q) with coordinate vector X PQ the ...
متن کاملSymmetry group, Hamiltonian equations and conservation laws of general three-dimensional anisotropic non-linear sourceless heat transfer equation
In this paper Lie point symmetries, Hamiltonian equations and conservation laws of general three-dimensional anisotropic non-linear sourceless heat transfer equation are investigated. First of all Lie symmetries are obtained by using the general method based on invariance condition of a system of differential equations under a prolonged vector field. Then the structure of symmetry ...
متن کاملCompressible Euler Equations with General Pressure Law
We study the hyperbolic system of Euler equations for an isentropic, compressible fluid governed by a general pressure law. The existence and regularity of the entropy kernel that generates the family of weak entropies is established by solving a new Euler-Poisson-Darboux equation, which is highly singular when the density of the fluid vanishes. New properties of cancellation of singularities i...
متن کاملPartial linear spaces built on hexagons
We define four families of geometries with as point graph the graph — or its complement — of all elliptic 4 hyperplanes of a given parabolic quadric in any finite 6-dimensional projective space, where adjacency is 5 given by intersecting in a tangent 4-space. One of the classes consists of semi-partial geometries constructed 6 in J.A. Thas [SPG-reguli and semipartial geometries, Adv. Geom. 1 (2...
