A question on the product of positive definite functions

Show that if $f$ and $g$ are continuous positive definite functions in $\mathbf{R}^1$, then $f(x)g(y)$ is positive definite on $\mathbf{R}^2$. I just wanted to check if the approach I’m using is correct, I defined the matrix $A_{j,k}=f(x_j-x_k)$ and $B_{j,k}=g(y_j-y_k)$ are positive definite functions for all $x_1 \cdots x_N$ and $y_1 \cdots y_N$. Would this imply […]
