Quantifier question?

700 Views Asked by At

How would I do the following quantifier and their negation

No one loves everybody.

or could you say : everybody does not love someone?

x is all people

So in symbolic this would be $\forall x, \exists y,$ x does not love y.

and the denial is

Someone loves everyone.

$\exists x,\forall y$, x loves y

My second ?

Everybody loves someone

$\forall x, \exists y$, x loves y

the denial

someone does not love everyone.

$\exists x, \forall y$, x does not love everyone.

The first is correct. But the notation can be improved. Usually we use an uppercase letter to represent a set and a lower case letter to represent an element in the set.

So a better way to state is "Let $X$ be all people." Then your first statement is:

$\forall x \in X, \exists y \in X$, such that $x$ does not love $y$.

Similar for other statements.

However, the denial for the second statement is a little off. It should be:

someone does not love anyone

or equivalently

someone loves no one.

The quantifier for the denial would be

$\exists x \in X, \forall y \in X$, $x$ does not love $y$.
