It’s trivial to check that if T is a Zp-lattice in a crystalline representation, then you can always find T’ which is non-crystalline and congruent to T modulo an arbitrarily high power of p. | |

| Nov 14, 2023 at 13:45 | comment | added | Will Sawin | How is the representation $V$ described in your data? A Galois representation is a priori an infinite amount of data - what do you actually have that you want to calculate with? | |
