Definition:Disjunction/General Definition

Definition
Let $p_1, p_2, \ldots, p_n$ be statements.

The disjunction of $p_1, p_2, \ldots, p_n$ is defined as:


 * $\displaystyle \bigvee_{i \mathop = 1}^n \ p_i = \begin{cases}

p_1 & : n = 1 \\ & \\ \displaystyle \left({\bigvee_{i \mathop = 1}^{n-1} \ p_i}\right) \lor p_n & : n > 1 \end{cases}$

That is:
 * $\displaystyle \bigvee_{i \mathop = 1}^n \ p_i = p_1 \lor p_2 \lor \cdots \lor p_{n-1} \lor p_n$

In terms of the set $P = \left\{{p_1, \ldots, p_n}\right\}$ this can also be rendered:


 * $\displaystyle \bigvee P$

and is referred to as the disjunction of $P$.

 * Disjunction is Associative which validates the construction.
