Solutions Manual for A First Course in Linear Model Theory, 2e by Nalini Ravishanker, Zhiyi Chi, Dipak Dey (All Chapters) 1.1 |a • b| = | − 9| = 9, while kak kbk = √ 6 √ 22 ∼= 11.489 > 9. 1.2 To verify the Cauchy–Schwarz inequality, first see that the inequality holds trivially if a and b are zero vectors. We therefore assume that both a and b are nonzero. Let c be the vector c = xa − yb, where x = b ′b, and y = a ′b. Clearly, c ′c ≥ 0. We express c ′c ...

In 1993, Czerwik [4] introduced the notion of a b-metric which is a generalization of a metric with a view of generalizing the Banach contraction map theorem. Definition 1.1 ([4]). Let X be a non-empty set and d : X × X −→ [0, +∞) be a function such that for all x, y, z ∈ X, (1) d(x, y) = 0 if and only if x = y. (2) d(x, y) = d(y, x). (3) d(x, z) ≤ 2[d(x, y) + d(y, z)]. Then d is called a b-metric on X and (X, d) is called a b-metric space. After that, in 1998, Czerwik [5] gen...
