Average liar count for degree-2 Frobenius pseudoprimes
In this paper we obtain lower and upper bounds on the average number of liars
for the Quadratic Frobenius Pseudoprime Test of Grantham, generalizing
arguments of Erd\H{o}s and Pomerance, and Monier. These bounds are provided for
both Jacobi symbol plus and minus cases, providing evidence for the existence
of several challenge pseudoprimes.Comment: 19 pages, published in Mathematics of Computation, revised version

Glimpse on the relationship between Feynman integral and integrable system
We briefly review recent attempts to relate the concept of Feynman integral and integrable systems. This constitutes an endeavour on our part in making the Feynman path integral into a mathematically meaningful entity
