. Extending this idea, conditions for the algebraic independence of several continued fractions are given. The proofs use the approximation properties of continued fractions in combination with the Thue-Siegel-Roth Theorem or a criterion for algebraic independence of Bundschuh. 相似文献

We obtain results showing that transcendental numbers of the form , wherea0, 1, is irrational, anda and are algebraic numbers, cannot be expressed algebraically in terms of two of the numbers. The proof is carried out by A. O. Gel'fond's method.Translated from Matematicheskie Zametki, Vol. 11, No. 6, pp. 635–644, June, 1972. 相似文献

In the semigroup algebra A of a finite inverse semigroup S over the field of complex numbers to an indempotent e there is assigned the sum (e)=e+(–1)KeL1eiK, where ei,...,em are maximal preidempotents of the idempotent e, and the summation goes over all nonempty subsets {i1,...,ik} of the set {1,...m} Then for any class K of conjugate group elements of the semigroup S the element K=a·(a–1a) (the summation goes over all ag) is a central element of the algebra A, and the set {K} of all possible such elements is a basis for the center of the algebra A.Translated from Zapiski Nauchnykh Seminarov Leningradskogo Otdeleniya Matematicheskogo Instituta im.

We reformulate part of the arguments of T. Geisser and M. Levine relating motivic cohomology with finite coefficients to
truncated étale cohomology with finite coefficients [9,10]. This reformulation amounts to a uniqueness theorem for motivic
cohomology, and shows that the Geisser-Levine method can be applied generally to compare motivic cohomology with other types
of cohomology theories. We apply this to prove an equivalence between conjectures of Tate and Beilinson on cycles in characteristic
p and a vanishing conjecture for continuous étale cohomology.

We generalize Gel'fond's criterion of algebraic independence by taking into account the values of the derivatives of the polynomials, and show how the new criterion applies to proving results of algebraic independence using interpolation determinants. We also establish a new result of approximation of a transcendental number by algebraic numbers of bounded degree and size. It contains an earlier result of E. Wirsing and also a result announced by A. Durand.

Let K be an algebraic number field, of degree n, with a completely ramifying prime p, and let t be a common divisor of n and . Then it is proved that if K does not contain the unique subfield, of degree t, of the p-th cyclotomic number field, then we have (hK, n) > 1, where hK is the class number of K. As applications, we give several results on hK of such algebraic number fields K. 相似文献

An algorithm is constructed for factoring polynomials in several variables over a finite field, which works in polynomial time in the size of the polynomial and q. Previously this result was known in the case of one variable. An algorithm is given for the solution (over the algebraic closure F of the field F) of systems of algebraic equations, where with working time of order where L is the size of a representative of the original system, is the degree of transcendence of the field F over the prime subfield, q=char(F). Previously the estimate was known for =0.Translated from Zapiski Nauchnykh Seminarov Leningradskogo Otdeleniya Matematicheskogo Instituta im. V. A. Steklova AN SSSR, Vol. 137, pp. 20–79, 1984. 相似文献

We give a variation of a theorem of Gelfond. One of the corollaries is Schneider's conjecture that either exp(e) or exp(e2) is transcendental. It also follows that at least one of the numbers exp(α), exp(α2), exp(α3) is transcendental for any nonzero complex number α. 相似文献
