Ajtai and Szemerédi proved the corners theorem, an important step toward higher dimensional generalizations of the Szemerédi theorem.

Fermat's theorem

The works of 17th century mathematician Pierre de Fermat engendered many theorems.

Harri Koskinen

Also very well known for the two variants of his Fatty container (models 7150 and 7100) designed in 1998 for Schmidinger; basically very expensive vinyl record carrying box and storage units respectively, made from Birch plywood with rounded corners as well as a well designed and finished construction.

Henry Baigent

The principal timber milled was white, red, and black pine, totara, rimu, and birch.

Henstock–Kurzweil integral

Cousin's theorem states that for every gauge \delta, such a \delta-fine partition P does exist, so this condition cannot be satisfied vacuously.

Hilbert's theorem

Hilbert's basis theorem, in commutative algebra, stating every ideal in the ring of multivariate polynomials over a Noetherian ring is finitely generated

Hilbert's irreducibility theorem, in number theory, concerning irreducible polynomials

Hilbert's syzygy theorem, a result of commutative algebra in connection with the syzygy problem of invariant theory

Hilbert's Theorem 90, an important result on cyclic extensions of fields that leads to Kummer theory

Kellogg's theorem

Kellogg's theorem is a pair of related results in the mathematical study of the regularity of harmonic functions on sufficiently smooth domains by Oliver Dimon Kellogg.

Kolmogorov–Smirnov test

This result may also be known as the Kolmogorov theorem; see Kolmogorov's theorem for disambiguation.

Kōmura's theorem, result on the differentiability of absolutely continuous Banach space-valued functions

Lafayette, Chippewa County, Wisconsin

The timber is small and thrifty - chiefly Maple, Birch Oak, Elm Ash and some small Pine.

Lake Mashū

On the slopes around and above the lake grow a mixture of evergreen forest with Picea jezoensis and Abies sachalinensis and birch forest with Betula ermanii.

Montel's theorem

For example, the first version of Montel's theorem stated above is the analog of Liouville's theorem, while the second version corresponds to Picard's theorem.

Morley's theorem

Morley's categoricity theorem, a theorem related to model theory, discovered by Michael D. Morley

Pfaffian function

In the 1990s, Alex Wilkie showed that one has the same result if instead of adding every analytic function, one just adds the exponential function to R to get the ordered real field with exponentiation, Rexp, a result known as Wilkie's theorem.

Pulverised fuel ash

The floral succession approximates to that of a coastal dune system, without the wind-blown deposition, so salt-tolerant plants are replaced by an attractive sward of legumes and perennials before turning to birch/willow scrub woodland.

Rado graph

Then, for any sets U and V, by the Chinese remainder theorem, the numbers that are quadratic resides modulo every prime in U and nonresidues modulo every prime in V form a periodic sequence, so by Dirichlet's theorem on primes in arithmetic progressions this number-theoretic graph has the extension property.

Representability

Brauer's theorem on the representability of zero by forms over certain fields in sufficiently many variables

Rock, Wood County, Wisconsin

The general character of this Township is 2d & 3d rate the soil is mostly poor loam & sand, the timber is mostly Birch Oak Aspen TamaracK & Pine the Pine is 2d growth & very poor.

Rouché's theorem

Theodor Estermann (1902–1991) proved in his book Complex Numbers and Functions the following relation: Let K\subset G be a bounded region with continuous boundary \partial K.

Savitch's theorem

In computational complexity theory, Savitch's theorem, proved by Walter Savitch in 1970, gives a relationship between deterministic and non-deterministic space complexity.

Sherry, Wisconsin

This Township is heavily Timbered with Maple Oak Birch & Pine Maple Oak & Birch being the prevailing Kinds - along the Border(?) of Mill Creek there is some good scattering Pine - along the Border(?) of the small stream (?) almost invariably(?) find alder thickets caused by Beaver dams.

Superslow process

Stagnation zones theorems are closely related to pre-Liouville's theorems about evaluation of solutions fluctuation, which direct consequences are the different versions of the classic Liouville theorem about conversion of the entire doubly periodic function into the identical constant.

Syamadas Mukhopadhyaya

Syamadas Mukhopadhyaya (June 22, 1866 – May 8, 1937) was an Indian mathematician who introduced the four-vertex theorem and Mukhopadhyaya's theorem in plane geometry.

Taylor's theorem

An earlier version of the result is already mentioned in 1671 by James Gregory.

The Records

Returning to the UK, Will Birch engaged the services of producer Craig Leon to record two new songs and to remix two tracks from Shades in Bed for a possible single release.

They were hired to back Stiff Records singer Rachel Sweet on the "Be Stiff Tour '78". The Records opened the shows with a set of their own. Birch and Wicks also wrote a song for Sweet's debut album entitled "Pin a Medal on Mary". The songwriting duo also penned "Hearts in Her Eyes" for the Searchers, who made an unexpected comeback with their power pop oriented album The Searchers in 1979.

Thévenin's theorem

The theorem was independently derived in 1853 by the German scientist Hermann von Helmholtz and in 1883 by Léon Charles Thévenin (1857–1926), an electrical engineer with France's national Postes et Télégraphes telecommunications organization.
