Projections in Spaces of Bimeasures
Canadian Mathematical Bulletin, 1988AbstractLet X and Y be metrizable compact spaces and μ and v be nonzero continuous measures on X and Y, respectively. Then there is no bounded operator from the space of bimeasures BM(X, Y) onto the closed subspace of BM(X, Y) generated by L1 (μ X v); in particular, if X and Fare nondiscrete locally compact groups, then there is no bounded projection ...

THEOREM 2. (a) HPn immerses in R8 n-Ea(n)-3J. (b) For n even, CPn immerses in R4ln-a(n)-1]. (c) For n odd, CPn immerses in R4n-a(n). Here a(n) is the number of ones in the dyadic expansion of n, and k(n) is a non-negative function depending only on the mod (8) residue class of n with k(1) = 0, k(3) = k(5) = 1 and k(7) = 4. As a consequence, for every j>

On the Embedding of an Affine Space into a Projective Space
Geometriae Dedicata, 2000Let \(k\) and \(K\) be commutative fields. An embedding of the affine space \(AG(n,k)\) into the projective space \(PG(m,K)\) is an injective mapping \(\psi\) from the point set of \(AG(n,k)\) to the point set of \(PG(m,K)\) which maps collinear points to collinear points and non-collinear points to non-collinear points. The author shows that for \(|k |

A new, non‐explosive actuator (NEA) developed by G&H Technology holds tensile loads of up to 12,500lb and quickly releases them when electronically activated. The Model 1203 actuator is stated to be safe, fast‐acting and highly reliable, and release occurs with minimum shock.
