Symbols:Vector Algebra

Vector Cross Product

 * $\times$

$\mathbf x \times \mathbf y$ means the cross product of $\mathbf x$ and $\mathbf y$, a binary operation on two vectors of a $3$-dimensional vector space which produces another such vector.

Vector Scalar Product

 * $\cdot$

$\mathbf x \cdot \mathbf y$ means the dot product of $\mathbf x$ and $\mathbf y$, a binary operation on two vectors which produces a scalar.

Del Operator

 * $\nabla$

 * $\wedge$

Some authors use $\mathbf A \wedge \mathbf B$ to mean $\mathbf A \times \mathbf B$, that is, the vector cross product.

The same symbol can be produced using, but this is usually used when the symbol is used in the sense of the logical and context.
