Outline: motivation, definition, and intuition behind metric spaces. redefining 18.100a real analysis and 18.100p real analysis in terms of metrics: open closed sets, convergence, cauchy sequences, and continuity. lecture 1: motivation, intuition, and examples (pdf).

Metric Space Examples Part 1 Youtube Example 1. the most basic example is r with d : r×r → r defined by d(x,y) = |x−y|. example 2. the example needed for multivariable calculus is rn with d : rn ×rn → r defined by d(x,y) = |x−y|, the length of x − y being defined as in the preceding section. in verifying that this really is a metric space, the only difficulty is. Notes on metric spaces. Freely sharing knowledge with learners and educators around the world. learn more. this course provides a basic introduction to metric spaces. it covers metrics, open and closed sets, continuous functions (in the topological sense), function spaces, completeness, and compactness. Lecture notes on metric spaces, g.adak 7.proposition: in any metric space (x, d), every open ball is an open set and every closed ball is a closedset. proof: suppose a ∈x, r > 0 where (x, d) is a metric space. we shall showthat b r (a) is open in(x, d). let p ∈b r (a ). thend p,a < .chooser 1 = r −d(p,a). then r 1 > 0. nowifx ∈b r 1.

Metric spaces: consolidated lecture notes semester i, 2023 24 example 1.1 unit circles in the three canonical spaces using the definitions of the canonical metrics equation 1.1, equation 1.2, and equation 1.3 (and a very loose understanding of a circle) we can draw the unit “circles” generated in r2 under each of these metrics. P. as in the first example above. we considered the case p = 1; so it is natural to ask about the case q = 1, where p and q are related as in our discussion of h¨older’s inequality. the relationship is 1 p 1 q = 1, and if q = 1 this gives 1 p = 0, which is nonsense of course. however, since 1 p → 0 as p → ∞, perhaps it makes sense to.
