In mathematics, especially in abstract algebra, a quasigroup is an algebraic structure resembling a group in the sense that "division" is always possible. Quasigroups differ from groups mainly in that they are not necessarily associative.
In topology, two continuous functions from one topological space to another are called homotopic if one can be "continuously deformed" into the other, such a deformation being called a homotopy between the two functions. A notable use of homotopy is the definition of homotopy groups and cohomotopy groups, important invariants in algebraic topology.
27 (twenty-seven) is the natural number following 26 and preceding 28.
Bags is the plural of bag.
Sound is an audible mechanical wave propagating through matter, or the perception of such waves by the brain.
Birdsongs of the Mesozoic is an American musical group founded in Boston, Massachusetts, United States, in 1980.
Rocker or rockers may refer to:
Latin squares and quasigroups are equivalent mathematical objects, although the former has a combinatorial nature while the latter is more algebraic. The listing below will consider the examples of some very small orders, which is the side length of the square, or the number of elements in the equivalent quasigroup.
The Analogs are a Polish street punk band. They originated in Szczecin, and are quite successful on the local and international punk rock scene.
Westport High School is located in Westport, Massachusetts, United States. It services students in grades 7-12. It is part of the Westport Community Schools.
Rick J. Jordan is an audio engineer, music producer and sound designer, who is most well known for his work in the German band Scooter.
Union Label Group is a record label based in Montreal, Quebec, Canada. It was formed through the merger of the smaller labels Stomp Records, 2112 Records, and Tyrant Records. Mayday! Records was later created as a genre imprint.
In the mathematical field of abstract algebra, isotopy is an equivalence relation used to classify the algebraic notion of loop.
Punk jazz describes the amalgamation of elements of the jazz tradition with the instrumentation or conceptual heritage of punk rock. John Zorn's band Naked City, James Chance and the Contortions, Lounge Lizards, Universal Congress Of, Laughing Clowns, Midori are notable examples of punk jazz artists.
Isotopes Punk Rock Baseball Club or commonly, The Isotopes, are a Canadian punk rock band, based in Vancouver, British Columbia. All of the band's songs pertain to the subject of baseball or baseball-related topics. They've released a few 7" EP's through Red Scare Records and have self-professed themselves The "World's Greatest Baseball Punk Band". January 2015, the band announced signing to Stomp Records and release of their debut album "Nuclear Strikezone". On April 14, 2017, the band is set to release their 2nd studio album "1994 World Series Champion" via Stomp/Destiny Records in North America and UK/Europe respectively.
In the theory of algebras over a field, mutation is a construction of a new binary operation related to the multiplication of the algebra. In specific cases the resulting algebra may be referred to as a homotope or an isotope of the original.
Modern Baseball was an American rock band from Philadelphia, Pennsylvania.
In mathematics, an isotopy from a possibly non-associative algebra A to another is a triple of bijective linear maps (a, b, c) such that if xy = z then a(x)b(y) = c(z). This is similar to the definition of an isotopy of loops, except that it must also preserve the linear structure of the algebra. For a = b = c this is the same as an isomorphism. The autotopy group of an algebra is the group of all isotopies to itself, which contains the group of automorphisms as a subgroup.
