Global warming has become a generally accepted theory in the past decade or so. A recent wave of severe storms has raised the question of whether global warming has or will result in an increase in both frequency and intensity of such extreme weather events. This paper will examine large-scale indicators that are generally believed to be closely related to(More)
The Plücker relations define a projective embedding of the Grass-mann variety Gr(p, n). We give another finite set of quadratic equations which defines the same embedding, and whose elements all have rank 6. This is achieved by constructing a certain finite set of linear maps V p k n → V 2 k 4 , and pulling back the unique Plücker relation on V 2 k 4. We(More)
The Plücker relations define a projective embedding of the Grass-mann variety Gr(k, n). We give another set of equations, which defines the same embedding, and whose elements all have rank 6 and are in fact obtained by pulling back the unique Plücker relation on 2 k 4. This is achieved through the construction of a finite set of linear maps k k n → 2 k 4(More)
