When asked that day whether the Government was condoning slavery of Chinese labourers in the Transvaal, Churchill replied: It has been used as a euphemism for a lie in the House of Commons, as
Representation of a Lie superalgebra Representation of a Lie superalgebra In the mathematical field of representation theory, a representation of a Lie superalgebra is an action of Lie superalgebra "L" on a Z-graded vector space "V", such that if "A" and "B" are any two pure elements of "L" and "X" and "Y" are any two pure elements of "V", then Equivalently, a representation of "L" is a Z-graded representation of the universal enveloping algebra of "L" which respects the third equation above. A Lie superalgebra is a complex Lie superalgebra equipped with an involutive antilinear map such that * respects the grading and A
