The project presented here emphasizes a specific biological problem affecting the salmon cage culture with the final goal being to propose a realistic management strategy for fjordic estuaries worldwide.
A geometric condition on differentiable maps is given which is
equivalent to the set of critical values being nowhere dense. In particular,
the geometric condition is satisfied for radially ductile maps.
On the other hand it is proved that the induced map on the de Rham
complex will be a...
In this dissertation we construct a homology theory on the category of submersions which generalizes the homology of the base space with coefficients in the homology of the fiber as given by the E²-terms of the Serre spectral sequence of a fiber bundle. The main motivation for this new homology...
In this dissertation we construct a homology spectral sequence
attached to a submersion whose E² term takes values in a certain
homology with local coefficients. The motivation for this work is
that the spectral sequence provides an effective tool for the conjecture
and proof of theorems regarding the global structure...
An obstruction theory is developed for "simplicial
bundles" which are generalized fiber bundles (over a
simplicial complex). Cross sections of one of the examples
of a simplicial bundle given (the Lefschetz bundle) are
essentially fixed point free maps of the base space.
Questionnaires were mailed to farmers in six counties of the
Willamette Valley requesting the kind and size of enterprises and the
gross income received from the enterprises on each farm.
Enterprises were defined both as general livestock or crop categories
and as individual crop or livestock enterprises. Two computer
programs...
