First one can quickly check that if X is a trivial topological space Another simple situation is of course the discrete topology: in this case no.
I am an algebraist with an interest in topology. The basic outline of this book corresponds to the syllabus of a first-year's course in algebraic topology
Topology underlies all of analysis and especially certain large spaces such as the dual of L1(Z) lead to topologies that cannot be described by metrics Topological spaces form the broadest regime in which the notion of a continuous function makes sense We can then formulate classical and basic
Part I ispoint{set topology, which is concerned with the more analytical and aspects of thetheory. Part II is an introduction toalgebraic topology, which associatesalgebraic structures such as groups to topological spaces. We will follow Munkres for the whole course, with some occassional addedtopics or dierent perspectives.
Topology is simply geometry rendered exible. In geometry and analysis, wehave the notion of a metric space, with distances specied between points.But if we wish, for example, to classify surfaces or knots, we want to thinkof the objects as rubbery. Examples.For a topologist, all triangles are the same, and they are all thesame as a circle.
Theorem 3.4(1) The product topology is the smallest topology such thatthe projections ofXYtoXandYare continuous. (2) A functionf: Z!XY, given byf(z) = (f1(z); f2(z)), is contin-uous i each of its coordinatesf1andf2are continuous. Proof. (2) It suces to check continuity using the basic open setsUVin XY. For these,f1(UV)=f1(U)f1
The answer is yes: in fact, ifXhas the trivial topology, then everysequence converges to every point, since the only nonempty open set isX.We sayXisHausdorif any pair of distinct points have disjoint neigh-borhoods. Inthiscase limits are unique!The Hausdor condition is one of theTrennungsaxioms; it is traditionallydenotedT2.
