This booklet introduces primary rules in arithmetic via intersting puzzles. scholars, from age12 upwards, who're uninterested in regimen classwork in maths will get pleasure from those puzzles on the way to sharpen will sharpen their logical reasoning. it truly is designed to arouse an curiosity in arithmetic between readers between readers within the 12-18 age staff.

If B is a product bundle, then X(B) = 0, whence X(B) = 0. 11) in (9), it follows that E induces a homo morphism . 1\ u which is univalent if and only if E-i(0)cPiTn(S*). 4) _1 This will be the case, for example, if q = 3 or 7, for then £ (0) = 0, or iff n < 2q—2 (11). Since E oJ = —J o i* we have E*\(B) = —JX(B). 4) is satisfied. -P. Serre (12, p. 498) that 7rr(Sq) is finite except when r = q or when r = 2q— 1 and g is even. Since n > 1 it follows that An>(Z is finite if n ^ g. If n = g, then £ * is univalent and E* AniQ c 7r 2fl (^ +1 ), which is finite.

T Cf. 1) in (10). 1) HOMOTOPY THEORY OF SPHERE BUNDLES OVER SPHERES 45 Let n > 1 and, as in § 1, let pq: ir^RJ -+ 7rn_1(iJa) be the automorphism induced by the map r->pqrpqi where pqeOq is the reflection in the hyperplane tq_x = 0. 1) with T replaced by T. Let 0: F w x F f l - > F n x F « be defined by 0(y,z) = (y,pqz). Since Pq a* = a« and Pq T(y)uq z = T'{y)Pq uqz = T(y)uq Pq z it follows that pq o g = g' o 0. The map 0 is of degree — 1. 10 in (1) that pqij = £+Aa, for some a e 7rn(£«). 3) that (-t g ) o J£ = -Jpqi = -J£+Poc.
