L1 as Probability space












0














In a continuous optimization problem, I consider the functions belonging to the "space of probabilities" on $lbrack 0,1 rbrack^N $ that admit a probability density. I understand that I exclude in the process distributions such as the Dirac.



Can I use a subset of the Lebesgue $L_1(lbrack 0,1 rbrack^N) $ space for that matter?
To be specific, can I use :
$$ { p in L_1 | int p = 1, pgeq0 } $$

  • Yes,you can. This identification is useful in many ways.

  • This is not fully accurate. What is the underlying space of $L_1$? What measure are integrating the function $p$ against?

  • Thanks both of you for your answers. $L_1$ is defined on $lbrack 0, 1 rbrack^N$ where N is an integer, and the measure is the Lebesgue measure. I will edit the question.
