Towers of congruences for linear recurrences at unramified primes, with a proof of P. Bala's conjecture on the tribonacci numbers

Let a(n) be a sequence of p-integral rationals satisfying a linear recurrence with monic characteristic polynomial f of degree d with integer coefficients, and let p be a prime not dividing the discriminant of f. Let D be the least common multiple of the degrees of the irreducibl...
