Using the formal derivative idea, we give a generalization for the Cauchys Theorem relating to the factors of (x + y)n–xn– yn. We determine the polynomials A(n, a, b) and B(n, a, b) such that the polynomial
can be expanded, for any natural number n, in terms of the polynomials x+y and ax2+bxy + ay2. We show that the coefficients of this expansion are intimately related to the Fibonacci, Lucas, Mersenne and Fermat sequences. As an application, we give an expansion for
as a polynomial in x+y and (xz –yt)(xt–yz). We use this expansion to find closely related identities to the sums of like powers. Also, we give two interesting expansions for the polynomials
and xn+yn that we call Fibonacci expansions and Lucas expansions respectively. We prove that the first coefficient of these two expansions is a Fibonacci sequence and a Lucas sequence respectively and the other coefficients are related sequences. Finally we give a generalization for all the previous results. 相似文献

In this article, we find elements of the Lucas polynomials by using two matrices. We extend the study to the n-step Lucas polynomials. Then the Lucas polynomials and their relationship are generalized in the paper. Furthermore, we give relationships between the Fibonacci polynomials and the Lucas polynomials. 相似文献

In 2006, Sanwong and Sullivan described the maximal congruences on the semigroup N consisting of all non-negative integers under standard multiplication, and on the semigroup T(X) consisting of all total transformations of an infinite set X under composition. Here, we determine all maximal congruences on the semigroup Zn under multiplication modulo n. And, when Y lohtain in X, we do the same for the semigroup T(X, Y) consisting of all elements of T(X) whose range is contained in Y. We also characterise the minimal congruences on T(X. Y). 相似文献

The properties of continued fractions, generalized golden sections, and generalized Fibonacci and Lucas numbers are proved on the ground of the properties of subsemigroups of the group of invertible integer matrices. Some properties of special recurrent sequences are studied. A new proof of the Pisot-Vijayaraghavan theorem is given. Some connections between continued fractions and Pisot numbers are considered. Some unsolved problems are stated. 相似文献
