Park City Lectures on Eigenfuntions
These lectures are devoted to nodal geometry of eigenfunctions φλ of the Laplacian ∆g of a Riemannian manifold (M, g) of dimension m and to the associated problems on L norms of eigenfunctions. The manifolds are generally assumed to be compact, although the problems can also be posed on non-compact complete Riemannian manifolds. The emphasis of these lectures is on real analytic Riemannian mani...
متن کاملNeighborhood poverty, park use, and park-based physical activity in a Southern California city.
A rich literature indicates that individuals of lower socio-economic status engage in less leisure time physical activity than individuals of higher socio-economic status. However, the source of the difference is believed to be, in part, due to differential access to resources that support physical activity. However, it has not been shown as to whether equal access to parks can mitigate differe...
متن کامل[Immature mosquitoes (Diptera: Culicidae) in a public city park].
OBJECTIVE To identify and compare the immature Culicidae population and their predators in different breeding places in a public city park. METHODS The study was carried out in an ecological park situated in the outskirts of the city of São Paulo, Brazil. Four Culicidae breeding places were selected: one semi-permanent, two permanent and one polluted brook. Throughout a year, at monthly inter...
متن کاملPark City Lectures on Mechanics, Dynamics, and Symmetry
i Preface In these five lectures, I cover selected items from the following topics: 1. Reduction theory for mechanical systems with symmetry, 2. Stability, bifurcation and underwater vehicle dynamics, 3. Systems with rolling constraints and locomotion, 4. Optimal control and stabilization of balance systems, 5. Variational integrators. Each topic itself could be expanded into several lectures, ...
متن کاملSpatial variation in ambient benzene concentrations over a city park.
Passive diffusive samplers were used to collect ambient benzene for a one-week sampling period (April 27 to May 4, 2011) at 11 locations throughout a city park in the Tampa, Florida, area. Concentrations were determined through gas chromatography with mass spectrometry. Spatial variability within the park and its contribution to uncertainty in health risk estimates were studied. Measured concen...
