Generalized j-planes
We construct and study a class of translation planes with kernel K ∼= GF (q), order q, and n > 2. These planes generalize the j-planes discovered by Johnson, Pomareda and Wilke in [14]. We show these planes are actually jj · · · j-planes. Hence, most of the results obtained in this article are on jj · · · j-planes. In fact, our study shows that these planes are either nearfield or new. An infin...
متن کاملGeometric structures arising from generalized j-planes
We study translation planes constructed by André net replacement on jj · · · jplanes and derivation on jj · · · j-planes. Then, we get to the conclusion that the family of non-André jj · · · j-planes is new, and thus so are their replaced and derived planes. We also study a new way to construct translation planes by putting together two ‘halves’ of planes that belong to two different jj · · · j...
متن کاملJ an 1 99 8 Vortices in coupled planes with columnar disorder and bosonic ladders
The phase diagram of two bosonic chains coupled by interchain hopping and interchain boson boson repulsion is investigated by means of bosonization and renormalization group techniques. It comprises two types of charge density waves, a conventional superfluid phase and a superfluid phase made of condensed boson pairs. The effect of a random potential on that system is also derived. Compared wit...

متن کاملOmittable Planes
In analogy to omittable lines in the plane, we initiate the study of omittable planes in 3-space. Given a collection of n planes in real projective 3-space, a plane Π is said to be omittable if Π is free of ordinary lines of intersection – in other words, if all the lines of intersection of Π with other planes from the collection come at the intersection of three or more planes. We provide two ...
