Monstrous Moonshine - Formal Versions of Conway's and Norton's Conjectures

Formal Versions of Conway's and Norton's Conjectures

The first conjecture made by Conway and Norton was the so-called "moonshine conjecture"; it states that there is an infinite-dimensional graded M-module

with for all m, where

From this it follows that every element g of M acts on each Vm and has character value

which can be used to construct the McKay–Thompson series of g:

The second conjecture of Conway and Norton then states that with V as above, for every element g of M, there is a genus zero subgroup K of PSL2(R), commensurable with the modular group Γ = PSL2(Z), such that is the normalized main modular function for K.

Famous quotes containing the words formal, versions, conway, norton and/or conjectures:

    The manifestation of poetry in external life is formal perfection. True sentiment grows within, and art must represent internal phenomena externally.
    Franz Grillparzer (1791–1872)

    The assumption must be that those who can see value only in tradition, or versions of it, deny man’s ability to adapt to changing circumstances.
    Stephen Bayley (b. 1951)

    Gentlemen, I give you a toast. Here’s my hope that Robert Conway will find his Shangri-La. Here’s my hope that we all find our Shangri-La.
    Robert Riskin (1897–1955)

    The question has been asked, “What is a woman?” A woman is a person who makes choices. A woman is a dreamer. A woman is a planner. A woman is a maker, and a molder. A woman is a person who makes choices. A woman builds bridges. A woman makes children and makes cars. A woman writes poetry and songs. A woman is a person who makes choices. You cannot even simply become a mother anymore. You must choose motherhood. Will you choose change? Can you become its vanguard?
    —Eleanor Holmes Norton (b. 1937)

    Our conjectures pass upon us for truths; we will know what we do not know, and often, what we cannot know: so mortifying to our pride is the base suspicion of ignorance.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
