New results on landscape boundaries [PDF]

Acta Geographica Debrecina. Landscape & Environment Series, 2011
The correct delineation of geographical and landscape ecological units, being the fundamental territorial domains of both physical and human geography, is very important from the aspect of several other related disciplines as well. It is hard to tell how

850 hPa Geopotential Height Link with Iraqi Precipitation and Temperature [PDF]

Revista Brasileira de Meteorologia
The study examines the connection between the geopotential height (Z850 hPa) and the temperature (°C) and precipitation (mm) in Iraq. The observation data for climatological parameters that are currently available from the Iraqi meteorological ...

Symplectic Homogenization

Journal de l’École polytechnique — Mathématiques, 2022
Let H(q,p) be a Hamiltonian on T * T n . Under suitable assumptions on H, we show that the sequence (H k ) k≥1 defined by H k (q,p)=H(kq,p) converges in the γ-topology—defined in [Vit92]—to an integrable continuous Hamiltonian H ¯(p). This is extended to the case of non-autonomous Hamiltonians, and the more general setting in which only some of the ...

Homogeneity degree of fans

, 2017
The homogeneity degree of a topological space $X$ is the number of orbits of the action of the homeomorphism group of $X$ on $X$. We initiate a study of dendroids of small homogeneity degree, beginning with fans.

Homomorphism–homogeneous graphs [PDF]

Journal of Graph Theory, 2010
AbstractWe answer two open questions posed by Cameron and Nesetril concerning homomorphism–homogeneous graphs. In particular we show, by giving a characterization of these graphs, that extendability to monomorphism or to homomorphism leads to the same class of graphs when defining homomorphism–homogeneity.
