Log-concavity and log-convexity of moments of averages of i.i.d. random variables
Philip Lamkin, Tomasz Tkocz
We show that the sequence of moments of order less than 1 of averages of i.i.d. positive random variables is log-concave. For moments of order at least 1, we conjecture that the se…

Strongly Non-zero Points and Elliptic Pseudoprimes
L. Babinkostova, D. Fillmore, P. Lamkin +2
We examine the notion of strongly non-zero points and use it as a tool in the study of several types of elliptic pseudoprimes. Moreover, we give give some probabilistic results abo…
