Lecture 1: Topology (International Winter School on Gravity and Light 2015)

As part of the world-wide celebrations of the 100th anniversary of Einstein's theory of general relativity and the International Year of Light 2015, the Scientific Organizing Committee makes available the central 24 lectures by Frederic P Schuller.
Titled "A thorough introduction to the theory of general relativity", the lectures introduce the mathematical and physical foundations of the theory in 24 self-contained lectures. The material is developed step by step from first principles and aims at an audience ranging from ambitious undergraduate students to beginning PhD students in mathematics and physics.
Satellite Lectures (see other videos on this channel) by Bernard F Schutz (Gravitational Waves), Domenico Giulini (Canonical Formulation of Gravity), Marcus C Werner (Gravitational Lensing) and Valeria Pettorino (Cosmic Microwave Background) expand on the topics of this central lecture course and take students to the research frontier.

  • I'm an Electronic Engineer, and I allways want to take a Course where you see Topology, Differential Geometry and Gravity, thenx, by the way, all those asking, what you need to know to understand this course, is just Set Theory and Read and Do Proofs, all the rest is explain.

  • Can such f() be defined that maps M to N and also the chosen topology on M to another topolgy on N?

    • @addemfrench thanks)

      Taras PokalchukTaras PokalchukVor 3 years
    • Sure, we typically define f from M to N and then look for various properties. The most important one is whether the inverse function maps open sets to open sets.

  • Great lecture! Wished I had such a competent professor when I studied math. I never really got it, cause lectures were bad. This here is explained easy and one can follow. What I like so much about topology is the fact that you don't need these annoying delta-epsilon-calculations to proove continuity :)

      giannisniper96giannisniper96Vor 3 years
    • Basic knowledge of differentiation etc. is needed when talking about smooth manifolds later on in the course. Lecture 4 I think.

      IndianHeathen1982IndianHeathen1982Vor 3 years
    • @IndianHeathen1982 Calculus is not necessary at all.

      Robert Wilson IIIRobert Wilson IIIVor 3 years
    • Calculus, linear algebra and some exposure to abstract algebra probably.

      IndianHeathen1982IndianHeathen1982Vor 3 years
    • Linear Algebra and Analysis; I recommend Linear Algebra by Levandosky, Principles of Mathematical Analysis by Rudin and Vector Calculus by Marsden and Tromba. You can skip these and go straight to Advanced Calculus by Loomis and Sternberg if you want too, this book will cover the content of this class though.

    • All you need is Linear Algebra and Analysis.

      Robert Wilson IIIRobert Wilson IIIVor 3 years
    • The math part cannot be understood without exposure to variational calculus (just the Euler-Lagrange eqns), multivariate calculus, and vector calculus on the level needed to understand maxwell's eqns, for example. The physics part requires exposure to special relativity, and again, some lagrangian mechanics would help.

      Jon ChuangJon ChuangVor 3 years
    • I think a basic knowlegde on sets, differential equations and calculus would be enough. These lectures are preparation for a bigger and more richer course on General Relativity, I think. So, if you want to learn more about GR, it would be a great start :)

      Clícia NaldoniClícia NaldoniVor 3 years
    • +adam landos I'm guessing this is a graduate level course, so a BS in physics or mathematics should suffice.

      Ingi Freyr AtlasonIngi Freyr AtlasonVor 4 years
    • +adam landos It is a good idea to have had some basic university level math courses like basic linear algebra and calculus courses. However they are not strictly required. You should also be able to make due with high school level mathematics with some difficulties.

  • I learned: a) The power set (P) of a set (M) is the set which contains all subsets of that set. u∈P(M) u⊆M b) A topology (O) can be defined on a set (M) as a subset of the power set -i) a topology must contain the set (M) and the empty set. ∅,M∈O (∴{∅,M}⊆O⊆P(M)) -ii) the intersection of any two members of a topology must also be a member of the topology. (v∩u)∈O | u,v∈O -iii) the union of any number of members of the topology must also result in a member of the topology. Ui(u)∈O | u∈O (is there any reason it needs to be an indexed set rather than simply v∪u like the previous axiom?) c) Members of a topology are called open sets d) A set is closed if it's compliment (relative in M) is an open set e) A map (f) from set M to set N is continuous if the preimage (with respect to f) of every open set in N is an open set in M (obviously requireing a topology in both). ∀V∈O:preim(V)∈O f) If we have 2 maps (f:M->N and g:N->P) and they're both continuous, then the composition of the two is also continuous. g) A subset (S) of a set with a topology can inherit that topology by taking the intersection of the subset and every element in the topology. Os = {u∩S|u∈O} h) If you restrict a continuous map to a specific subset in the domain and inherit the topology, then the restricted map is still continuous. Nice synopsis for such a long video eh?

    • @The Destroyer A set is closed if and only if its complement is open, so either direction works.

      Jared TramontanoJared TramontanoVor 3 years
    • I think d) is the reverse?

      The DestroyerThe DestroyerVor 3 years
    • +BlackEyedGhost Of Course the index set is needed! What you've written only says the topology contains finite unions of members... It must contain arbitrary unions

    • @Christer Holmstén So far, I've found that @9400754094) by Norbert Straumann to be the closest in spirit to his lectures, but Schuller's video presentation here is the best and most clear and well-organized (solid?) presentation out there on General Relativity, vs. lecture note, textbook, other media. I really think it's even reference worthy. By the way, I write notes up about these lectures here: drive.google.com/file/d/0B1H1Ygkr4EWJbF9mQXluQVVQTDg/view?usp=sharing and on my wordpress.com blog: ernestyalumni.wordpress.com/2015/05/25/20150524-update-on-gravity_notes-tex-pdf-notes-and-sage-math-implementation-of-lecture-1-tutorial-1-topology-for-the-we-heraeus-international-winter-school-on-gravity-and-light-2015/
