Here I am on google scholar citations.
There is a constant 1.369451... named after me. It is not as important as Euler's constant. Here is a Maple file to compute some estimates of it. Recently Sadov computed many more digits.
There are two different sequences named after me. The first appeared in D. Boyd, Linear recurrence relations for some generalized Pisot sequences, Advances in Number Theory, Oxford University Press, 1993, pp. 333-340, and is defined as follows: a0 = 8, a1 = 55, and for n ≥ 1 we have an+1 is the least integer such that an+1/an > an/an–1. The sequence starts 8, 55, 379, 2612, 18002, ... and appears to satisfy the recurrence an = 6an–1 + 7an–2 – 5an–3 – 6an–4. But it does not; the identity fails at n = 11056. See here for more details.
The second is actually a family of sequences, defined here by Moree et al.
