Maya maize godLike other Mesoamerican peoples, the traditional Maya recognize in their staple crop, maize, a vital force with which they strongly identify. This is clearly shown by their mythological traditions. According to the 16th-century Popol Vuh, the Hero Twins have maize plants for alter egos and man himself is created from maize. The discovery and opening of the Maize Mountain – the place where the corn seeds are hidden – is still one of the most popular of Maya tales. In the Classic period (200-900 AD), the maize deity shows aspects of a culture hero.
Mayan languagesThe Mayan languages form a language family spoken in Mesoamerica, both in the south of Mexico and northern Central America. Mayan languages are spoken by at least 6 million Maya people, primarily in Guatemala, Mexico, Belize, El Salvador and Honduras. In 1996, Guatemala formally recognized 21 Mayan languages by name, and Mexico recognizes eight within its territory. The Mayan language family is one of the best-documented and most studied in the Americas.
IxchelIxchel or Ix Chel (iʃˈt͡ʃel) is the 16th-century name of the aged jaguar Goddess of midwifery and medicine in ancient Maya culture. In a similar parallel, she corresponds, to Toci Yoalticitl "Our Grandmother the Nocturnal Physician", an Aztec earth Goddess inhabiting the sweatbath, and is related to another Aztec Goddess invoked at birth, viz. Cihuacoatl (or Ilamatecuhtli). In Taube's revised Schellhas-Zimmermann classification of codical deities, Ixchel corresponds to the Goddess O.
Mesoamerican writing systemsMesoamerica, along with Mesopotamia and China, is one of three known places in the world where writing is thought to have developed independently. Mesoamerican scripts deciphered to date are a combination of logographic and syllabic systems. They are often called hieroglyphs due to the iconic shapes of many of the glyphs, a pattern superficially similar to Egyptian hieroglyphs. Fifteen distinct writing systems have been identified in pre-Columbian Mesoamerica, many from a single inscription.
Dresden CodexThe Dresden Codex is a Maya book, which was believed to be the oldest surviving book written in the Americas, dating to the 11th or 12th century. However, in September 2018 it was proven that the Maya Codex of Mexico, previously known as the Grolier Codex, is, in fact, older by about a century. The codex was rediscovered in the city of Dresden, Germany, hence the book's present name. It is located in the museum of the Saxon State Library.
Group representationIn the mathematical field of representation theory, group representations describe abstract groups in terms of bijective linear transformations of a vector space to itself (i.e. vector space automorphisms); in particular, they can be used to represent group elements as invertible matrices so that the group operation can be represented by matrix multiplication. In chemistry, a group representation can relate mathematical group elements to symmetric rotations and reflections of molecules.
Representation theoryRepresentation theory is a branch of mathematics that studies abstract algebraic structures by representing their elements as linear transformations of vector spaces, and studies modules over these abstract algebraic structures. In essence, a representation makes an abstract algebraic object more concrete by describing its elements by matrices and their algebraic operations (for example, matrix addition, matrix multiplication).
Computer visionComputer vision tasks include methods for , , and understanding digital images, and extraction of high-dimensional data from the real world in order to produce numerical or symbolic information, e.g. in the forms of decisions. Understanding in this context means the transformation of visual images (the input to the retina in the human analog) into descriptions of the world that make sense to thought processes and can elicit appropriate action.
Irreducible representationIn mathematics, specifically in the representation theory of groups and algebras, an irreducible representation or irrep of an algebraic structure is a nonzero representation that has no proper nontrivial subrepresentation , with closed under the action of . Every finite-dimensional unitary representation on a Hilbert space is the direct sum of irreducible representations. Irreducible representations are always indecomposable (i.e. cannot be decomposed further into a direct sum of representations), but the converse may not hold, e.
TzolkʼinTzolkʼin (t͡sol ˈkʼin, formerly and commonly tzolkin) is the name bestowed by Mayanists on the 260-day Mesoamerican calendar originated by the Maya civilization of pre-Columbian Mesoamerica. The tzolkʼin, the basic cycle of the Maya calendar, is a preeminent component in the society and rituals of the ancient and the modern Maya. The tzolkʼin is still used by several Maya communities in the Guatemalan highlands. While its use has been spreading in this region, this practice is opposed by Evangelical Christian converts in some Maya communities.
