    going to help so many students who are always rushed to do graph theory at the end of their classes during the semester!

    thanks WoM. my professor is speaking Mars language, so I come here to listen to you.

      Thanks a lot for watching Chian! Your comment cracked me up, but I’m sorry to hear your professor has not been making things clear! I hope my lessons will continue to be helpful!

    this lecture is far better than my professor's lecture tbh
    its precise and clear

      Out of curiosity, what is/was your degree and how are/were your studies going?

      That song at the end is extremely soothing as well.

    Is it appropriate to consider E(H) as a subset of E(G) when defining a spanning subgraph? If E(H) happens to contain all the edges of G, won't it then become an improper subgraph?

    • @vongolaprimo6520
      @vongolaprimo6520 หลายเดือนก่อน

      if so, then improper subgraph can be considered as a spanning subgraph?

    What is connected Spanning subgraph? Do they have Cycles?

    Spanning subgraph? More like "Superb knowledge transference; thanks for that!" 🙏

    Love this playlist of short, crisp bite-sized videos covering basics of graph-theory; kudos!.
    QUESTION on this video: The video appears to suggest that any subset of the edges in the original ghraph would make it a spanning sub-graph so long as all the vertices of the original graph are retained. I was under the impression that the edges must be such that every vertex that is reachable in the original graph must be reachable in the sub-graph for it to be a 'SPANNING' sub-graph. Am I mistaken?

    • @WrathofMath
      @WrathofMath  ปีที่แล้ว

      Thank you! And from every source I can find, the definition I provide in this video is the one that is used. A spanning subgraph of G is a subgraph of G with the same vertex set as G.

      that has special term for it, "spanning tree"

    THANK YOU! I REQUEST YOU TO MAKE VIDEOS ON TOPOLOGY 😊🙏

    • @WrathofMath
      @WrathofMath  3 ปีที่แล้ว +1

      You're welcome! Videos on topology will come in the future, but for this year my focus is on real analysis! I still have considerable studying to do myself for topology, so it will be a while unfortunately.

    If you wanted to determine how many isolated vertices H (the spanning subgraph) would have how would you do this?

  • @ugashinipreethi2620
    @ugashinipreethi2620 2 ปีที่แล้ว +1

    Is original graph itself a spanning subgraph ?

    • @PunmasterSTP
      @PunmasterSTP 7 หลายเดือนก่อน

      Yes, I believe that is true.

  • @mathisawesome618
    @mathisawesome618 4 ปีที่แล้ว

    does it still need to be connected?

    • @WrathofMath
      @WrathofMath  4 ปีที่แล้ว +1

      Thanks for watching and nope, a spanning subgraph just has to be a subgraph with all vertices of the original graph - no other restrictions!

    Sir, spanning subgraph has nothing to do with the edges right? Is it just the vertices?

    Sir if u have a solution manual for A First course in Graph Theory by Gary Chartrand and Ping Zhang
    It would be very helpful if u can
    By the way the videos are very useful
    Thank u for all that u are doing spreading ur knowledge

    • @WrathofMath
      @WrathofMath  4 ปีที่แล้ว +1

      Thanks for watching and I am glad the videos have been useful! I do not have a solution manual for A First Course in Graph Theory, but I have many videos giving my own solutions to exercises from the text. If you have a particular problem from the text in mind, let me know and I can point you to, or possibly make a new lesson on it!
