In mid-60s Marvel comics, not only did Vietnam exist, but American soldiers got blinded there and students on Spider-Man's campus protested against the war.
Therefore not only do wolves not exist, but there must be a conspiracy between wolf experts, the lupine risk assessment board and the manufacturers of bite-proof trousers to convince the rest of us that they do.
There are millions of us out here who not only don't turn to God to attend to our needs, but don't believe such an entity exists.
Then J ∈ J ( X, P ) L ∩ J ( X, P ) R. Indeed, we see that condition ( 1) does not hold only if there exist some α ∈ A and u, v, w ∈ X such that J α ( u, w ) = c α, J α ( u, v ) = p α ( u, v ), J α ( v, w ) = p α ( v, w ) and p α ( u, v ) + p α ( v, w ) < c α.
A knowledge base (mathcal {K}) is satisfiable (respectively, unsatisfiable) if and only if there exists (respectively, there does not exist) a model for (mathcal {K}).
However, when we look at the definition of σ-roots in the quadratic case, it is clear that (f(x)) does not have a σ-root if and only if there does not exist (t inmathbb{C}) such that (tsigma(t)+ a_{1}t + a_{0} = 0).
Poverty and inequality doesn't only exist 'over there'.
((sum_{j=0}^{m}F_{j},sum_{j=0}^{m}G_{j}mid C)) is exactly observable if and only if there does not exist (0neq Zin S^{n(m+1)}) such that overline{F}'Zoverline{F}+overline{G}'Zoverline{G}= lambda Z, qquad CZ=0.
Furthermore, the quadratic (f(x) = x^{2}+a_{1}x+a_{0}) is irreducible in (mathbb{C}[x; sigma]) if and only if there does not exist some (t inmathbb{C}) such that (tsigma(t) +a_{1}t +a_{0} = 0).
By the PBH criterion for complete observability, (2.14) is completely observable if and only if there does not exist an eigenvector (xineq0) in (frac{n(m+1)[n(m+1)+1]}{2}) dimensions such that widetilde{mathcal{L}}(mathcal{L}_{F,G})xi=theta(H_{n,m}) xi=lambda xi, quad (Iotimes C H_{n,m}xi=0.
DMU p is called to be efficient in T v if and only if there does not exist another (x, y) ∊ T v such that (−x, y) ≥ (−x p, y p ) and (−x, y) ≠ (−x p, y p ), otherwise, DMU p is called inefficient.
