... it, an object with no indices is just a scalar, a quantity that does not transform at all under a rotation or any other vector transformation. In this context all of these objects, and also those with more than two indices, are given a new name: they are called tensors. Tensors are distinguished by ...

... 2. (a) Let P and Q denote points in R3 with position vectors p and q respectively. Find the position vector a of a point A on the line through P and Q which is 3 times as far from Q as from P : does this fix the point A uniquely? (b) Consider a triangle ABC. Let M be a point on AB such that BM = 2M ...

... Theorem 3 should be. Bárány and Grinberg [1] claim that they can replace 2d by 2d − 1. On the other hand, the upper bound cannot be smaller than d, as the d-dimensional L1 space shows [1]. As the negative part of Theorem 5 and the results of [5] show, an online method would have to have a (suffici ...

The purpose of this chapter is to introduce Hilbert spaces, and more precisely the Hilbert spaces on the field of complex numbers, which represent the abstract environment in which Quantum Mechanics is developed. To arrive at Hilbert spaces, we proceed gradually, beginning with spaces mathematically ...

... (iii) S is closed under scalar multiplication. For let [x, y] ∈ S and t ∈ R. Then x = 2y and hence tx = 2(ty). Consequently [tx, ty] = t[x, y] ∈ S. (b) Let S be the set of vectors [x, y] satisfying x = 2y and 2x = y. Then S is a subspace of R2 . This can be proved in the same way as (a), or alternat ...
