  1. What is infinity divided by infinity? - Mathematics Stack Exchange

    Aug 11, 2012 · I know that $\\infty/\\infty$ is not generally defined. However, if we have 2 equal infinities divided by each other, would it be 1? if we have an infinity divided by another half-as …

  2. elementary set theory - What do finite, infinite, countable, not ...

    A set A A is infinite, if it is not finite. The term countable is somewhat ambiguous. (1) I would say that countable and countably infinite are the same. That is, a set A A is countable (countably …

  3. I have learned that 1/0 is infinity, why isn't it minus infinity?

    An infinite number? Kind of, because I can keep going around infinitely. However, I never actually give away that sweet. This is why people say that 1 / 0 "tends to" infinity - we can't really use …

  4. Infinity plus Infinity - Mathematics Stack Exchange

    In terms of set theory, it is true that for any infinite power K:k+k=kk=k. note that for a=0 : ak=0 and not infinity

  5. linear algebra - What, exactly, does it take to make an infinite ...

    Oct 31, 2017 · If your infinite dimensional space has an inner product and is complete with respect to the induced norm then it is an infinite dimensional Hilbert space. That's all it takes to …

  7. Is there a case "infinite" p-group is meaningful?

    An infinite dimensional vector space over a field with p p elements is probably the simplest example. But there are some really wacky groups called "Tarski Monsters" that provide …

  8. Example of infinite field of characteristic $p\\neq 0$

    Can you give me an example of infinite field of characteristic p ≠ 0 p ≠ 0? Thanks.

  9. What is the difference between "infinite" and "transfinite"?

    Jun 6, 2020 · The reason being, especially in the non-standard analysis case, that "infinite number" is sort of awkward and can make people think about ∞ ∞ or infinite cardinals …

  10. Subspaces of an infinite dimensional vector space

    If V V is an infinite dimensional vector spaces, then it has an infinite basis. Any proper subset of that basis spans a proper subspace whose dimension is the cardinality of the subset. So, …
