Representing Integers as Sums of Squares
We study in detail the special case of Waring’s problem when the power k = 2. Ultimately, we prove that four is the least number of squares needed to represent any integer. To this end, we prove that some numbers cannot be represented as sums of two squares, some cannot be represented as sums of three, and all can be represented as sums of four. We also show that numbers of a certain form can b...
متن کاملSome Ideas for Final Projects
1.8. Investigate algorithms for expressing an integer as a sum of squares. We have determined exactly which integers are sums of two squares. Later on in the course we will prove which integers are sums of four squares (Lagrange’s theorem) and state without proof which integers are sums of three squares (Legendre-Gauss theorem). But these methods do not give efficient algorithms for actually fi...
متن کاملGeometryof Numbers Proof of Goo tzky’s Four-Squares Theorem
The totally positive algebraic integers of certain number fields have been shown to be the sums of four squares of integers from their respective fields. The case ofQð ffiffiffi 5 p Þ was demonstrated by Götzky and the cases of Qð ffiffiffi 2 p Þ and Qð ffiffiffi 3 p Þ were demonstrated by Cohn. In the latter situation, only those integers with even coefficient on the radical term could possibl...
متن کاملParametric model based assessment of genotype×environment interactions for grain yield in durum wheat under irrigation
The objectives of this study were to assess the genotype (G) by environment (E) interaction of grain yield of durum wheat(Triticum durum Desf.) based on parametric models, additive main effects and multiplicative interaction (AMMI) and joint linear regression models; and compare the relative efficiency of the two models in explaining the GE effects. Twenty-three genotypes were evaluated across ...
متن کاملAn alternate proof of Cohn’s four squares theorem
While various techniques have been used to demonstrate the classical four squares theorem for the rational integers, the method of modular forms of two variables has been the standard way of dealing with sums of squares problems for integers in quadratic fields. The case of representations by sums of four squares in Qð ffiffiffi 5 p Þ was resolved by Götzky, while those of Qð ffiffiffi 2 p Þ an...
