A magyar mezőgazdaság az elmúlt egy-két évtizedben nem volt olyan kedvező gazdasági kondícióban, mint az elmúlt három évben. A kedvező helyzet kialakulásában közrejátszott a mezőgazdasági termékek termelői árainak emelkedése, az EU támogatási rendszere és a több mint...

We discuss conditions for the Aubin property of solutions to perturbed cone constrained programs, by using and refining results given in Klatte and Kummer (Nonsmooth equations in optimization. Kluwer, Dordrecht, <CitationRef CitationID="CR10">2002</CitationRef>). In particular, we show that constraint nondegeneracy and hence uniqueness of...</citationref>

We present an alternative proof of the Mountain Pass Theorem by means of the classical Ekeland Variational Principle for a class of <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$${\mathcal{C}^1}$$</EquationSource> </InlineEquation> -functionals. In this new proof we avoid the machinery of convex analysis by a simpler characterization of the critical values of the...</equationsource></inlineequation>
