    PN surfaces and their convolutions with rational surfaces

  • Original language description

    Rationally parameterized hypersurfaces can be classified with respect to their RC properties (Rational Convolutions) with the help of the Gr"{o}bner bases theory. This classification focuses on special classes of rational parameterizations which providea rational description of convolution hypersurfaces generally (GRC parameterizations), or just in some special cases (SRC parameterizations). The main aim of this paper is to bring the theory of the so called PN surfaces (surfaces with Pythagorean Normal vectors) and their PN parameterizations (parameterizations fulfilling the PN condition) in relation to the theory of SRC parameterizations and to show that this type of parameterizations can be further classified with respect to the degree of the construction of convolution surfaces. The connection of SRC PN parameterizations to the well known concepts of proper and square-root parameterizations is also investigated.

    PN plochy a jejich konvoluce s racionálními plochami

  • Czech description

    Racionální nadplochy mohou být dále klasifikovány vzhledem k tzv. RC podmínkám, a to s využitím Groebneroých bází. tato klasifikace se zaměřuje na speciální třídy parametrizací, které poskytují racionální konvoluce obecně (GRC parametrizace) nebo ve speciálních případech (SRC parametrizace). Našim hlavním cílem je propojit uvedenou teorii s teorií PN ploch a následně roztřídit PN parametrizace podle odpovídajících konvolučních stupňů. V článku jsou rovněž studovány souvislosti s tzv. "proper" a "square-root" parametrizacemi.
