- How to prove that something is the supremum of a set? - Physics Forums
True well, this is what I've thought of we know that because A is a bounded subset of R the supremum exists since for any a in A we have: -sqrt(2)<2x+sqrt(2)y<2+2sqrt(2) then if a>=2+2sqrt(2) or a<=-sqrt(2) then a is not a member of A therefore the set U={a in R: a>=2+2sqrt(2)} is the set of the upper bounds by definition of U, It's clear that 2+sqrt(2) is the minimum of the set and

- Infimum Supremum: Learn the Difference! - Physics Forums
If the supremum is IN the set, then it is the maximum of the set If the infimum in IN the set, then it is the minimum of the set But the supremum does not have to be in a set in which case the set would not have a maximum The supremum and infimum of the intervals (0,1), [0,1), (0,1], and [0,1] are 0 and 1 respectively for all four intervals
- Where can I find a proof of the supremum norm as a norm? - Physics Forums
The supremum norm is also known as the uniform, Chebychev or the infinity norm Physics news on Phys org A new type of X-point radiator that prevents tokamaks from overheating
- Is the Supremum Proof of 0. 999. . . = 1 Flawed? - Physics Forums
Computing that supremum is the idea of the proof The actual proof consists of actually carrying out the relatively easy computation (assuming it's being presented in a context where calculation is expected to be so obvious trivial it can be emitted)
- Prove that a nonempty finite contains its Supremum - Physics Forums
Prove that a nonempty finite [itex]S\,\subseteq\,\mathbb{R}[ itex] contains its Supremum If S is a finite subset of ℝ less than or equal to ℝ, then ∃ a value "t" belonging to S such that t ≥ s where s ∈ S This is the only way I see to prove it, I hope your help Regards
- Does the Supremum of the Set A Exist? - Physics Forums
Prove the supremum exists :) Homework Statement Let A = {x:x in Q, x^3 < 2} Prove that sup A exists Guess the value of sup A The Attempt at a Solution First we show that it is non-empty We see that there is an element, 1 in the set, thus A is non-empty Now we show that A is
- Supremum inside and outside a probability - Physics Forums
I want to know the relation between the two probabilities, since, it seems to me that in such a case, the supremum of the absolute difference and the supremum of the probability would be obtained with the same x, i e the x in the domain that bears the greatest absolute difference
