It seems to me like topology is totally a mathematical construct since the idea of an "open set" in an abstract space seems to have no "physical" meaning outside of Euclidean spaces. A locally path-connected space is also locally connected. If not, do you know a counterexample? Because their trajectories satisfy Hudson's definition of continuity but not mine, the space-time trajectories are said to be “connected, but not path-connected”, and curves like this are standard counterexamples in topology. Over 140 examples, preceded by a succinct exposition of general topology and basic terminology. Counterexamples In Topology - Steen , Seebach. A locally connected space is not locally path-connected in general. LCH space which is not a compact metric space, you can search the Questions in Topology from the Topology Atlas, where you can Ask a Topologist See also Lynn Arthur Steen and J. I am looking for a non-continuous function f:X-->Y where X,Y are non-countable spaces, but where lim n-->∞ xn = x. Does not contain a non-trivial Cartesian product of two sets that are open in the co-compact topology. Does it mean a morphism which is a surjection of sheaves in the fpqc topology? Arthur Seebach, Jr, Counterexamples in Topology, Springer, 1978, for zillions of counterexamples. In that case you get counter examples by looking at ind schemes (for example the functor of morphisms A^1 —> A^1). If necessary $X$ and $Y$ can be surfaces Browse other questions tagged general-topology algebraic-geometry schemes or ask your own question. (Only one of them is satisfied and 3 examples for each property.). A naive approach to the problem of constructing “convenient categories” usually runs into problems. So, can anyone give me 2 counter examples(best simple) of non-homeomorphic map $f$ between 2 topological space but satisfy the properties I give? So this is not a counterexample to Theorem 2. Each example treated as a whole. The definitions of the separation axioms I used to make these are taken from Counterexamples In Topology.
