Hello,<br><br>I'm dealing with products of large polynomial exponentials. However, whenever a product of two exponential terms appears they are not "simplified" into an exponential of a sum (unless the exponential args are numeric). Is there some way to coerce this to happen? Specifically I have a situation like this:<br>
<br>exp(T-t_1)*exp(T-t_2) <br><br>and I want something like this:<br><br>exp(2T-t_1-t_2)<br><br>or even<br><br>exp(2T) exp(-t_1) exp(-t_2)<br><br><br>I'm porting some of ginac's functionality to python (using cython), and I've been accessing ginac through that, so it's possible it's a bug on my side. However, I've tried to get the desired behavior in ginsh with no luck, so I'm guessing the default behavior is to not simplify products of exponentials. I've also tried creating a possymbol called "e" and simply raising it to the needed power, but this has the same behavior as the exp function. I've been using ginac1.6.1<br>
<br>Thanks,<br>Levi<br>
