Inductive McKay Condition in defining Characteristic
We reformulate the inductive McKay condition, from Isaacs-Malle-Navarro, and
apply the new criterion to simple groups of Lie type, when the prime is the
defining characteristic p. Thereby we make use of a recent result of Maslowski.
This proves that these simple group satisfy the inductive McKay condition for
p. In the non simply-laced types and non-classical types this reproves earlier
results by Brunat and Brunat-Himstedt.Comment: 12 page
Sooty blotch of apple: Efficacy of different application strategies
Sooty blotch causes heavy losses in Lake Constance organic apple production. In the last
five years research has been done at the research station for fruit growing
(Kompetenzzentrum Obstbau â Bodensee) on strategies to control Sooty blotch on organic
grown pome fruit. Different control strategies with lime sulphur, coconut soap and
potassium bicarbonate with different application rates, application times were tested in
several trials on the cultivar âTopazâ. Over the years the results show that lime sulphur has
significant effects in controlling Sooty blotch. In a first trial potassium bicarbonate showed
a promising efficacy against Sooty blotch. Concerning the right application times we need
further investigations. The problem is that Sooty blotch is a disease complex caused by
several fungi and it is likely that the fungi that are a part of the complex differ from area to
area
Spartacus - MĂ€nnermuskeln, Heldenbilder oder: die Befreiung der Moral
"Spartacus", das ist der Mann mit dem entschlossenen Blick aus stahlblauen Augen, ein Gesicht mit klassisch-gerader Nase und darunter ein eckiges Kinn mit unĂŒbersehbarem GrĂŒbchen, ein Körper mit muskolösen nackten Armen und Schenkeln - "Spartacus" ist fĂŒr viele der Filmschauspieler Kirk Douglas in einer seiner bekanntesten Rollen, in Spartacus von Stanley Kubrick (USA, 1960)
Invariant blocks under coprime actions
If a finite group acts coprimely as automorphisms on a finite group ,
then the -invariant Brauer -blocks of are exactly those that contain
-invariant irreducible characters
Least squares fitting with rotated paraboloids
In [1] the problem of estimating the parameters of a rotated parabola fitted to measured points in the plane was examined. The
corresponding method, also used in [2,3], is extended
here to the case of a rotated paraboloid. Fitting by such a surface occurs in computational metrology e.g. when some parabolic reflector will be checked to be a good one
Least-squares fitting of parametric curves with a linear function of several variables as argument
We discuss fitting of a parametric curve in the plane in the
least-squares sense when the independent variable is a linear function of several variables with unknown coefficients. A general numerical method is recommended. For two special models the algorithmic details and numerical examples are given
Fitting affine and orthogonal transformations between two sets of points
Let two point sets P and Q be given in . We determine a
translation and an affine transformation or an isometry such that the image of Q approximates P as best as possible in the least squares sense
