Let be a finite abelian extension of number fields with imaginary quadratic. Let be the ring of integers of and a rational integer. We construct a submodule in the higher odd-degree algebraic -groups of using corresponding Gross’s special elements. We show that this submodule is of finite index and prove that this index can be computed using the higher “twisted” class number of , which is the cardinal of the finite algebraic -group .

The Cauchy problem for the system of linear generalized ordinary differential equations in the J. Kurzweil sense , with a unique solution is considered. Necessary and sufficient conditions are obtained for a sequence of the Cauchy problems , to have a unique solution for any sufficiently large such that uniformly on . Presented results are analogous to the sufficient conditions due to Z. Opial for linear ordinary differential systems....

We consider digit expansions with an endomorphism of an Abelian group. In such a numeral system, the -NAF condition (each block of consecutive digits contains at most one nonzero) is shown to minimise the Hamming weight over all expansions with the same digit set if and only if it fulfills the subadditivity condition (the sum of every two expansions of weight admits an optimal -NAF). This result is then applied to imaginary quadratic bases, which are used for scalar...

This thesis is concerned with the problem of determining a measure of algebraic independence for a particular m-tuple θ₁,..., of complex numbers. Specifically, let K be a number field and let f₁(z),..., be elements of K[[z]] algebraically independent over K(z) satisfying equations of the form(*) (j = i,...,m)for b ≥ 2, , in K(z). Suppose finally that α ∈ K is such that 0 < |α| < 1, the ) converge at z = α and the , are analytic at Then the are algebraically independent...

The value of was determined for many particular Pisot numbers and for the golden number. In this paper the value of is determined for irrational numbers , satisfying with a positive integer .

Let be a square-free positive integer and be the class number of the real quadratic field We give an explicit lower bound for , where . Ankeny and Chowla proved that if is a natural number and is a square-free integer, then whenever . Applying our lower bounds, we show that there does not exist any natural number such that . We also obtain a similar result for the family . As another application, we deduce some criteria for a class group of prime power order to be...
