Question:
Why do we consider Lebesgue spaces for $p$ greater than and equal to $1$ only and not for $p$ any real number?
Now provide the response and nothing else.
| The reason is that we would like to define a norm by the following formula:$$\|f\|_p:=\left(\int_X |f|^p d\mu \right)^{1/p}.$$Therefore, we need to have triangle inequality (Minkowski's Inequality) which is available only for $p\geq 1$.
