 Lee, J. ., & Vélez, W. (1992). Integral solutions in arithmetic progression for y^{2}=x^{3}+k. Periodica Mathematica Hungarica, 25(1), 3149.More infoAbstract: Integral solutions to y 2=x 3+k, where either the x's or the y's, or both, are in arithmetic progression are studied. When both the x's and the y's are in arithmetic progression, then this situation is completely solved. One set of solutions where the y's formed an arithmetic progression of length 4 had already been constructed. In this paper, we construct infinitely many sets of solutions where there are 4 x's in arithmetic progression and we disprove Mohanty's Conjecture [8] by constructing infinitely many sets of solutions where there are 4, 5 and 6 y's in arithmetic progression. © 1992 Akadémiai Kiadó.

Journal of Number Theory, 19(2), 283294.More infoAbstract: Let L F be a finite separable extension, L* = L{0}, and T( L* F*) the torsion subgroup of L* F*. When L F is an abelian extension T( L* F*) is explicitly determined. This information is used to study the structure of T( L* F*). In particular, T( F(α)* F*) when am = a ∈ F is explicitly determined. © 1984.
 Orozco, M. d., & Vélez, W. Y. (1982). The lattice of subfields of a radical extension. Journal of Number Theory, 15(3), 388405.More infoAbstract: Let xm  a be irreducible over F with char F{does not divide}m and let α be a root of xm  a. The purpose of this paper is to study the lattice of subfields of F(α) F and to this end C( F(α) F, k) is defined to be the number of subfields of F(α) of degree k over F. C( F(α) F, pn) is explicitly determined for p a prime and the following structure theorem for the lattice of subfields is proved. Let N be the maximal normal subfield of F(α) over F and set n = N : F, then C( F(α) F, k) = C( F(α) F, (k, n)) = C( N F, (k, n)). The irreducible binomials xs  b, xs  c are said to be equivalent if there exist roots βs = b, γs = a such that F(β) = F(γ). All the mutually inequivalent binomials which have roots in F(α) are determined. Finally these results are applied to the study of normal binomials and those irreducible binomials x2e  a which are normal over F (char F ≠ 2) together with their Galois groups are characterized. © 1982.
 Mann, H. B., & Vélez, W. Y. (1976). Prime ideal decomposition in {Mathematical expression}. Monatshefte für Mathematik, 81(2), 131139.More infoAbstract: Let F be an algebraic number field and μ∈F such that xmμ is irreducible, where m is an integer. Let {Mathematical expression} be a prime ideal in F with {Mathematical expression}. The prime decomposition of {Mathematical expression} in {Mathematical expression} is explicitly obtained in the following cases. Case 1: {Mathematical expression}, (a,m) = 1 (where {Mathematical expression} means {Mathematical expression}, ς ≢ 0 {Mathematical expression}). Case 2:m ≡lt, where l is a prime and l ≢ 0 {Mathematical expression}. Case 3:m ≢ 0 {Mathematical expression} and every prime that divides m also divides pf1. It is not assumed that the vth roots of unity are in F for any v ≠ 2. © 1976 SpringerVerlag.
