Lemma 1: For all codewords, in a Walsh – Hadamard code,,, where represent the bits in in positions and respectively, and represents the bit at position.
Lemma and C
The fact that there can not be any limit points of the set except in closed intervals follows from the argument used in Lemma 1, namely, that near any tangent point in the C-plane the curves C and Af are analytic, and therefore the difference between them must be a monotone function in some neighborhood on either side of the tangent point.
In this way, Yoneda's Lemma provides a complete classification of all natural transformations from the functor Hom ( A ,-) to an arbitrary functor F: C → Set.
Lemma: Let A ∈ C < sup > n × n </ sup > be a complex-valued matrix, ρ ( A ) its spectral radius and ||·|| a consistent matrix norm ; then, for each k ∈ N:
Lemma and .
Further, we see by Lemma 2 that the multiplicity of F can only change at a tangent point, and at such a point can only change by an even integer.
We have proved that φ is either satisfiable or refutable, and this concludes the proof of the Lemma.
As shown by the Lemma above, we only need to prove our theorem for formulas φ in R of degree 1. φ cannot be of degree 0, since formulas in R have no free variables and don't use constant symbols.
Pavel Samuilovich Urysohn, Pavel Uryson () ( February 3, 1898, Odessa – August 17, 1924, Batz-sur-Mer ) was a Jewish mathematician who is best known for his contributions in the theory of dimension, and for developing Urysohn's Metrization Theorem and Urysohn's Lemma, both of which are fundamental results in topology.
He also gives starting at Lemma 4 and Proposition 40 ) the theory of the motions of comets ( for which much data came from John Flamsteed and from Edmond Halley ), and accounts for the tides, attempting quantitative estimates of the contributions of the Sun and Moon to the tidal motions ; and offers the first theory of the precession of the equinoxes.

Conditions for Lemma 2 shall hold for all factor, any violation will result in satisfying the condition of Lemma 1 whereby the result has been proven.
Ngô Bảo Châu proved an auxiliary but difficult statement, the so-called " Fundamental Lemma ", originally conjectured by Langlands.
Singleton and bound
The Singleton bound is that the sum of the rate and the relative distance of a block code cannot be much larger than 1:
In coding theory, the Singleton bound, named after Richard Collom Singleton, is a relatively crude bound on the size of a block code with block length, size and minimum distance.
Block codes that achieve equality in Singleton bound are called MDS ( maximum distance separable ) codes.

Singleton and code
Despite having already created a substantial amount of new game code — essentially all the above engines --, Singleton was involved in numerous other game projects at the time and thus put the game on hiatus.
