Comparison of smallest eigenvalues and extremal points for third and fourth order three point boundary value problems.
… with a variation of the fourth order problem. Extremal points via Krein-Rutman theory are then found. Analogous results are then obtained for the eigenvalue problems u‴ + λ₁p(x)u = 0 and u‴ + λ₂q(x)u = 0, with each satisfying u(0) = u′(r) = u″(1) = 0, 0 < 1/2 < r < 1.

Positive Solutions, Existence Of Smallest Eigenvalues, And Comparison Of Smallest Eigenvalues Of A Fourth Order Three Point Boundary Value Problem
… eigenvalues is then applied to characterize extremal points of the differential equation $u^{(4)} + q(t)u = 0$ satisfying boundary conditions $u(0) = u'(p) = u''(b) = u'''(b)= 0$ where $1-\frac{ </p>

Giant Magnetoresistance in Multilayers
… contributions to the conductance due to various extremal points on the Fermi surface were studied. Finally, the ballistic conductance and GMR were found to saturate quickly with the number of periods in the multilayer. Next, we investigated the angular dependence of the conductance and giant …
