| Feb 15, 2012 at 17:02 | comment | added | Martin Brandenburg | This property is not preserved under the "naive product" which is no product at all (see details in Question B). The category has products by some abstract result (Todd, Theo or Mike probably can explain this?). | |
| Feb 15, 2012 at 16:51 | comment | added | Angelo | I don't know a precise reference, but it's a very well known fact. I doubt that the category of representations of $\mathbb{G}_{\mathrm a}$ has infinite products: (algebraic) representations of algebraic groups are unions of finite-dimensional subrepresentations, and this property is not preserved under infinite products. | |
