The actual structure of language—its grammar in fact—is more or less different from the various descriptions of that structure which have been called grammar, sometimes extremely so, and that includes operator grammar. Confusion of formalisms with that which is formalized is still pretty common. Recent work by Stephen Johnson at Columbia and NYU, showing rules etc. as emergent phenomena, is touched on toward the end of that essay (doi 10.1075/hl.00077.nev). Most of the math you probably won’t find relevant to your interests. Suffice to say, it doesn’t support the notion that grammar is control of program perceptions.
