Its only nonzero entries are 1 and -1. I'm trying to use the right_kernel command to calculate its kernel over the rational numbers. However, whenever I run the code, I get a message that says "the kernel appears to have died. It will restart automatically." Does this mean I'm running out of memory on my computer? Any ideas on how to address this? All this is done in a Jupyter notebook. Thank you!ClaudiaYunWed, 06 Nov 2019 11:15:57 -0600http://ask.sagemath.org/question/48650/
