Among the topics are variation on the p-Laplacian, extremal functions in Poincare-Sobolev inequalities for functions of bounded variation, homocline
type solutions for a class of differential equations with periodic coefficients, the cooperative case of quasilinear and singular systems, weighted asymmetric problems for an indefinite elliptic operator, multiple non-trivial solutions of the Dirichlet problem for the prescribed mean curvature equation, and existence of nodal solutions for some nonlinear elliptic problems.
The thickness of the Voronka aquifer is 10-40 m in the Estonian Homocline.
The hydraulic conductivity of aquifers on the Estonian Homocline varies within 0.5-13 m/d and transmissivity within 25-1000 [m.sup.2]/d.
The local groundwater flow on the Estonian Homocline follows from the regional flow pattern.
And this is not the case, as the Carboniferous formation constitutes a homocline
along the whole south-western boundary of the ISS.
The sedimentary bedrock strata have a regular southward inclination (7-15', azimuth 179[degrees]) and Palaeozoic layers form a gently dipping homocline
. Several escarpments of erosional origin, locally known as klints (North-Estonian, West-Estonian and Upper-Devonian) and smaller scarps have been formed in accordance with lithological differences and tectonical structures in the bedrock.
The Piusa-Tabina area is located within the SE marginal zone of the gentle slope of the Fennoscandian Shield where the sedimentary cover forms a uniform Estonian Homocline
(Puura & Vaher 1997).
These are generally interpreted as remnants of the cratonic crust that was rifted during Mesoproterozoic extension, the eastern limit of which may be reflected in a prominent series of west-facing crustal-scale homoclines
beneath the Foreland Belt.
