  2. Butterfly graph - Wikipedia

    en.wikipedia.org/wiki/Butterfly_graph

    In the mathematical field of graph theory, the butterfly graph (also called the bowtie graph and the hourglass graph) is a planar, undirected graph with 5 vertices and 6 edges. [ 1 ] [ 2 ] It can be constructed by joining 2 copies of the cycle graph C 3 with a common vertex and is therefore isomorphic to the friendship graph F 2 .

    The butterfly curve is a transcendental plane curve discovered by Temple H. Fay of University of Southern Mississippi in 1989. [1] Equation

  4. Butterfly diagram - Wikipedia

    en.wikipedia.org/wiki/Butterfly_diagram

    Signal-flow graph connecting the inputs x (left) to the outputs y that depend on them (right) for a "butterfly" step of a radix-2 Cooley–Tukey FFT. This diagram resembles a butterfly (as in the morpho butterfly shown for comparison), hence the name, although in some countries it is also called the hourglass diagram.

  5. Desmos - Wikipedia

    en.wikipedia.org/wiki/Desmos

    In November 2023, Desmos gave users the ability to bring sound to their graphs, allowing them to produce tones of a given frequency and gain. [14] Users can create accounts and save the graphs and plots that they have created to them. A permalink can then be generated which allows users to share their graphs and elect to be considered for staff ...

    A bridgeless or isthmus-free graph is a graph that has no bridge edges (i.e., isthmi); that is, each connected component is a 2-edge-connected graph. butterfly 1. The butterfly graph has five vertices and six edges; it is formed by two triangles that share a vertex. 2.

  8. Hofstadter's butterfly - Wikipedia

    en.wikipedia.org/wiki/Hofstadter's_butterfly

    In condensed matter physics, Hofstadter's butterfly is a graph of the spectral properties of non-interacting two-dimensional electrons in a perpendicular magnetic field in a lattice. The fractal, self-similar nature of the spectrum was discovered in the 1976 Ph.D. work of Douglas Hofstadter [ 1 ] and is one of the early examples of modern ...

  9. Butterfly curve (algebraic) - Wikipedia

    en.wikipedia.org/wiki/Butterfly_curve_(algebraic)

    In mathematics, the algebraic butterfly curve is a plane algebraic curve of degree six, given by the equation x 6 + y 6 = x 2 . {\displaystyle x^{6}+y^{6}=x^{2}.} The butterfly curve has a single singularity with delta invariant three, which means it is a curve of genus seven.
