The Coolidge-Nagata conjecture holds for curves with more than four cusps [PDF]

open access: yes, 2012
Let E be a plane rational curve defined over complex numbers which has only locally irreducible singularities. The Coolidge-Nagata conjecture states that E is rectifiable, i.e.

Plucker-Clebsch formula in higher dimension

open access: yes, 2010
Let $S\subset\Ps^r$ ($r\geq 5$) be a nondegenerate, irreducible, smooth, complex, projective surface of degree $d$. Let $\delta_S$ be the number of double points of a general projection of $S$ to $\Ps^4$. In the present paper we prove that $ \delta_S\leq{

Extra-Curricular Physical Activities and Physical Self-Perceptions in British 14ñ15-Year-Old Male and Female Adolescents

European Physical Education Review, 2002
This investigation considers the differences in physical self-perceptions between participants and non-participants in extra-curricular physical activities. Pupils ( N= 1130) from schools in England and Wales were asked to complete the Children and Youth Physical Self-Perception Profile (1995) and a questionnaire containing physical activity items ...

Some combinatorial aspects of S^1 fixed points of Peterson varieties

, 2017
In this paper we investigate the partial order set An of S 1 fixed points of the Peterson variety Petn, a special subset of involutions of symmetric group Sn. The order is induced by the Bruhat order of Sn.

Investigation of cross‐contamination during Si‐implantion in GaAs with SIMS

, 1988
The contamination of Si-implantation in GaAs was analysed with SIMS. This was done by measuring the molecules composed of the ‘contamination-atoms’ and the matrix atoms.
