  2. Hyperbolic tree - Wikipedia

    en.wikipedia.org/wiki/Hyperbolic_tree

    Drawing the tree as a node-link diagram thus requires exponential amounts of space to be displayed. One approach is to use a hyperbolic tree, first introduced by Lamping et al. [1] Hyperbolic trees employ hyperbolic space, which intrinsically has "more room" than Euclidean space. For instance, linearly increasing the radius of a circle in ...

  3. Baum test - Wikipedia

    en.wikipedia.org/wiki/Baum_test

    The first step is to let the participant draw a tree on a paper. In some cases, participants are also asked to write a short essay about the drawn tree. [7] A psychologist or a psychiatrist will then evaluate the various aspects of the drawing as well as the individual's behavior or comments while completing the test.

    However, the drawing shows little resemblance to the latter. Historians suggest that many of the backdrops of the drawings were copied from drawing manuals. One such example is a drawing of the greater mousedeer, the background of which shows a leafless climber attached to a rock. Some scholars query this, as mousedeer do not live in such rocky ...

  6. Radial tree - Wikipedia

    en.wikipedia.org/wiki/Radial_tree

    Example of a radial tree, from a 1924 organization chart that emphasizes a central authority [1]. A radial tree, or radial map, is a method of displaying a tree structure (e.g., a tree data structure) in a way that expands outwards, radially.

  7. Cayley's formula - Wikipedia

    en.wikipedia.org/wiki/Cayley's_formula

    Each labelled rooted forest can be turned into a labelled tree with one extra vertex, by adding a vertex with label n + 1 and connecting it to all roots of the trees in the forest. There is a close connection with rooted forests and parking functions , since the number of parking functions on n cars is also ( n + 1) n − 1 .

    Trees and forests provide a habitat for many species of animals and plants. Tropical rainforests are among the most biodiverse habitats in the world. Trees provide shade and shelter, timber for construction, fuel for cooking and heating, and fruit for food as well as having many other uses. In much of the world, forests are shrinking as trees ...

    Just-As-High says that Yggdrasil is the biggest and best of all trees, that its branches extend out over all of the world and reach out over the sky. Three of the roots of the tree support it, and these three roots also extend extremely far: one "is among the Æsir , the second among the frost jötnar, and the third over Niflheim .
