  2. Dynkin diagram - Wikipedia

    en.wikipedia.org/wiki/Dynkin_diagram

    Removing a node from a connected diagram may yield a connected diagram (simple Lie algebra), if the node is a leaf, or a disconnected diagram (semisimple but not simple Lie algebra), with either two or three components (the latter for D n and E n). At the level of Lie algebras, these inclusions correspond to sub-Lie algebras.

  3. Knights and Knaves - Wikipedia

    en.wikipedia.org/wiki/Knights_and_Knaves

    Alice says, "We are both knaves”. In this case, Alice is a knave and Bob is a knight. Alice's statement cannot be true, because a knave admitting to being a knave would be the same as a liar telling the truth that "I am a liar", which is known as the liar paradox.

  4. Child lying - Wikipedia

    en.wikipedia.org/wiki/Child_lying

    An honest lie (or confabulation) is defined by verbal statements or actions that inaccurately describe history, background, and present situations. Perjury is the act of lying or making verifiably false statements on a material matter under oath or affirmation in a court of law, or in any of various sworn statements in writing. White lies are ...

    For many purposes, it is only necessary to know that an expansion for in terms of iterated commutators of and exists; the exact coefficients are often irrelevant. (See, for example, the discussion of the relationship between Lie group and Lie algebra homomorphisms in Section 5.2 of Hall's book, [2] where the precise coefficients play no role in the argument.)

  7. Closed-subgroup theorem - Wikipedia

    en.wikipedia.org/wiki/Closed-subgroup_theorem

    It states that if H is a closed subgroup of a Lie group G, then H is an embedded Lie group with the smooth structure (and hence the group topology) agreeing with the embedding. [ 1 ] [ 2 ] [ 3 ] One of several results known as Cartan's theorem , it was first published in 1930 by Élie Cartan , [ 4 ] who was inspired by John von Neumann 's 1929 ...
