Interim report on the ground-water resources of Seminole County, Florida
Salt-water encroachment is undoubtedly the problem of most concern to
users of ground water in Florida. This is a problem in many coastal areas
where water levels are lowered excessively by heavy pumping. It is a
problem also in some inland areas where the water-bearing formations contain
salty water at relatively shallow depths. Among the coastal areas where wells
have become contaminated with salt water are Pinellas County and the Miami
area of Dade County. Inland areas where wells are likely to become contaminated
with salt water include Seminole County and the southwestern part
of Volusia County.
The purpose of the investigation is to make a detailed study of the
geology and ground-water resources of the county with special emphasis on
the problems associated with declining water levels and salt-water
contamination. This report reviews briefly the progress of the investigation
through February 1954. (PDF contains 43 pages.
The density of rational points on non-singular hypersurfaces, II
For any integers , let be a non-singular hypersurface of degree that is defined over . The main result in this paper is a proof that the number of -rational points on which have height at most satisfies
for any . The implied constant in this estimate depends at most upon and
Plane curves in boxes and equal sums of two powers
Given an absolutely irreducible ternary form , the purpose of this paper
is to produce better upper bounds for the number of integer solutions to the
equation F=0, that are restricted to lie in very lopsided boxes. As an
application of the main result, a new paucity estimate is obtained for equal
sums of two like powers.Comment: 15 pages; to appear in Math. Zei
Quadratic polynomials represented by norm forms
The Hasse principle and weak approximation is established for equations of
the shape P(t)=N(x_1,x_2,x_3,x_4), where P is an irreducible quadratic
polynomial in one variable and N is a norm form associated to a quartic
extension of the rationals containing the roots of P. The proof uses analytic
methods.Comment: 55 page
