In this paper, we establish the following two results: (1) a skew translation generalized quadrangle of even order is quadrangle, (2) does not admit point regular group automorphisms. The first result confirms conjecture Payne (1975) based on earlier work Ott (2021), and second Ghinelli (1992).

STOCK DEFINITION AND GEOGRAPHIC RANGE The common dolphin may be one of the most widely distributed species of cetaceans, as it is found world-wide in temperate, tropical, and subtropical seas. In the North Atlantic, common dolphins appears to be present along the coast over the continental shelf along the 200-300 m isobaths or over prominent underwater topography from 50E N to 40ES latitude (Ev...

We explore the connection between black hole spin and AGN power by addressing the consequences underlying the assumption in the recent literature that the gap region between accretion disks and black holes is fundamental in producing strong, spin-dependent, horizon-threading magnetic fields. Under the additional assumption that jets and outflows in AGN are produced by the BlandfordZnajek and Bl...

The convergence to steady states of non-negative solutions u to the one-dimensional viscous Hamilton-Jacobi equation ∂tu − ∂2 xu = |∂xu|, (t, x) ∈ (0,∞)× (−1, 1) with homogeneous Dirichlet boundary conditions is investigated. For that purpose, a Liapunov functional is constructed by the approach of Zelenyak (1968). Instantaneous extinction of ∂xu on a subinterval of (−1, 1) is also shown for su...
