EN 202 : Problem Set 1 Douglas

As discussed in class on 1/27/06, this is a nonhomogeneous constant-coefficient partial differential equation (PDE) of the form aux + buy = f(x, y), where a = b = 1. In particular, this question asks us to solve the Cauchy problem – one which is defined on the entire real line. Using the method presented in class, it is a straightforward process to determine the general solution u(x, y). First,...

EN 257 : Applied Stochastic Processes Problem Set 5 Douglas

The members of a sequence of jointly independent random variables X[n] have probability density functions of the following form. f X (x; n) = 1 − 1 n 1 √ 2πσ exp − 1 2σ 2 x − n − 1 n σ 2 + 1 n σ exp(−σx)u(x) Determine whether or not the random sequence X[n] converges in (a) the mean-square sense, (b) probability, (c) distribution. Recall, from Definition 6.7-5 on page 379 in [4], that a random ...

Generalized Douglas-Weyl Finsler Metrics

In this paper, we study generalized Douglas-Weyl Finsler metrics. We find some conditions under which the class of generalized Douglas-Weyl (&alpha, &beta)-metric with vanishing S-curvature reduce to the class of Berwald metrics.

On Special Generalized Douglas-Weyl Metrics

In this paper, we study a special class of generalized Douglas-Weyl metrics whose Douglas curvature is constant along any Finslerian geodesic. We prove that for every Landsberg metric in this class of Finsler metrics, ? = 0 if and only if H = 0. Then we show that every Finsler metric of non-zero isotropic flag curvature in this class of metrics is a Riemannian if and only if ? = 0.
