Elliptic sequences and Pfaffian Triples
Abstract: Elliptic sequences -- a generalization of elliptic divisibility sequences -- can be defined by an infinite number of three term homogeneous fourth degree algebraic equations each of which is determined by a triple of quadruples of positive integers which I have named Pfaffian triples. I have recently discovered some combinatorial properties of Pfaffian triples which relate them to sequences in the On-Line Encyclopedia of Integer sequences (OEIS). A brief introduction to Elliptic sequence and Pfaffian triples is found in my Essay "In the Elliptic Realm" which is on the web.Time: Friday, February 13, 2015, 3:30-4:20 p.m.
