For example, the cohomology ring of a path-connected H-space with finitely generated and free cohomology groups is a Hopf algebra. Also, one can define the Pontryagin product on the homology groups of an H-space. The fundamental group of an H-space is abelian. To see this, let X be an H-space with identity e and let f and g be loops at e.
Free-space path loss. In telecommunication, the free-space path loss ( FSPL) (also known as free-space loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air).

NASA Helios. The NASA Pathfinder and NASA Pathfinder Plus were the first two aircraft developed as part of an evolutionary series of solar - and fuel-cell -system-powered unmanned aerial vehicles. AeroVironment, Inc. developed the vehicles under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) program.
Path space fibration. In algebraic topology, the path space fibration over a based space [1] is a fibration of the form [2] where. is the based path space of X; that is, equipped with the compact-open topology. The free path space of X, that is, , consists of all maps from I to X that may not preserve the base points, and the fibration given by ...

An equivalent definition of homotopical connectivity is based on the homotopy groups of the space. A space is n-connected (or n-simple connected) if its first n homotopy groups are trivial. Homotopical connectivity is defined for maps, too. A map is n -connected if it is an isomorphism "up to dimension n, in homotopy ".
Myspace (formerly stylized as MySpace; also myspace and sometimes my␣, with an elongated open box symbol) is a social networking service based in the United States. Launched on August 1, 2003, it was the first social network to reach a global audience and had a significant influence on technology, pop culture and music. [2]
