In this paper we consider a class of logarithmic Schrödinger equations with a potential which may change sign. When the potential is coercive, we obtain infinitely many solutions by adapting some arguments of the Fountain theorem, and in the case of bounded potential we obtain a ground state solution, i.e.

In this work we study the Cauchy problem of a fourth-order nonlinear Schrödinger equation which arises from certain physical applications. We consider only the cases n=1,2,3n=1,2,3.

The asymptotic form for large $|t|$ can be obtained by applying the method of stationary phase to the integral stated above. Since the phase $\vec{p}\cdot \vec{x}-\epsilon_{\vec{p}} t$ is rapdily varying as function of $\vec{p}$ when t (and possibly also $\vec{x}$ is large, the dominant contribution to the integral comes from the point: $\vec{p.

"A book of great value it should have a profound influence upon future research."--Mathematical Reviews. Hardcover edition. The foundations of the study of asymptotic series in the theory of differential equations were laid by Poincaré in the late 19th century, but it was not until the middle of this century that it became apparent how essential asymptotic series are to understanding.

More precisely, the asymptotic paths of the solitons are determined and their position- and phase-shifts are computed explicitly. As a corollary we generalize the conservation law known for the N. random variable — is a special case of the other key convergence concept for asymptotic theory, convergence in probability.

Following Ruud’s text, we deﬁne convergence in probability of the sequence of random vectors XNto the (nonrandom) vector x, denoted plim N→∞ XN= x or XN →p x as N →∞ if XN →d x, i.e., FN(x) →1{0 ≤x}. The complete theory is given by Weyl [H.

ASYMPTOTIC LINES. George Adams was interested in asymptotic lines as possible interfaces between physical and ethereal forces.

In terms of counterspace this might be equivalent to a linkage between space and counterspace. An asymptotic line is a kind of boundary between positive and negative curvature on a surface. For example, consider a ruled hyperboloid. A simple model of Up: lecture_6 Previous: lecture_6 Predicting energy levels and probabilities: The Schrödinger equation.

In the last lecture, we saw that the Bohr model is able to predict the allowed energies of any single-electron atom or cation. In a previous paper [2] the authors have given a method for estimating the coefficients of a single equation in a complete system of linear stochastic equations.

In the present paper the consistency of the estimates and the asymptotic distributions of the estimates and the test criteria are studied under conditions more general than those used.
