Thus every shear matrix has an inverse, and the inverse is simply a shear matrix with the shear element negated, representing a shear transformation in the opposite direction. In fact, this is part of an easily derived more general result: if S is a shear matrix with shear element λ , then S n is a shear matrix whose shear element is simply n λ .
In mathematics, a geometric algebra (also known as a Clifford algebra) is an algebra that can represent and manipulate geometrical objects such as vectors. Geometric algebra is built out of two fundamental operations, addition and the geometric product. Multiplication of vectors results in higher-dimensional objects called multivectors ...
The Timoshenko–Ehrenfest beam theory was developed by Stephen Timoshenko and Paul Ehrenfest [1] [2] [3] early in the 20th century. [ 4 ] [ 5 ] The model takes into account shear deformation and rotational bending effects, making it suitable for describing the behaviour of thick beams, sandwich composite beams , or beams subject to high ...
first conformally projecting x from e 123 onto a unit 3-sphere in the space e + ∧ e 123 (in 5-D this is in the subspace r ⋅ (−n o − 1 / 2 n ∞) = 0); then lift this into a projective space, by adjoining e – = 1, and identifying all points on the same ray from the origin (in 5-D this is in the subspace r ⋅ (−n o − 1 ...

The Schur complement is named after Issai Schur [1] who used it to prove Schur's lemma, although it had been used previously. [2] Emilie Virginia Haynsworth was the first to call it the Schur complement. [3] The Schur complement is sometimes referred to as the Feshbach map after a physicist Herman Feshbach. [4]
A two dimensional Minkowski space, i.e. a flat space with one time and one spatial dimension, has a two-dimensional Poincaré group IO(1,1) as its symmetry group.The respective Lie algebra is called the Poincaré algebra.
