The present paper owes a great debt to Strang's work.
Recent work of Kirby shows that......
Kirk, building on work of Penot, developed a more abstract version of......
The name of Harald Bohr is attached to bG in recognition of his work on almost periodic functions.
With a little more work we can prove......
[see also: succeed] In addition to illustrating how our formulas work in practice, it provides a counterexample to Brown's conjecture.
The method works regardless of whether A or B is used.
The argument works equally well for R being a general ring with unity.
A further complication arises from “selection'', which works rather differently from the other labels.
We can assume that p is as close to q as is necessary for the following proof to work.
The definition of generator is designed to make the proof above work for M=Z.
Also, wherever possible, we work with integer coefficients, enabling us to obtain information about torsion.
In practice, D is usually too large a set to work with.
We now work toward the establishment of properties (A) to (D).
In Section 4 we worked out a fairly detailed picture of linear H-systems.
