Mock theta functions' parity-type conjecture
Mock theta functions' parity-type conjecture
Let be a mock theta function with integer coefficients, and let denote the coefficient of in its series expansion. Say that is of parity type if the proportions of indices for which is even and odd are respectively and , and of parity type if those proportions are respectively and . Mock theta functions' parity-type conjecture. The functions , , , , , , , , , , , , , , , , , , and are all of parity type . The four functions , , , and are all of parity type . The conjecture is based on computations and known properties; for the latter four functions, one parity subsequence is almost always even and the complementary subsequence is odd half of the time. The paper also notes that the assertion for is equivalent to the assertion for .
