Date: Monday ; Time: ; Location: building B-8, room 0. We consider a level-set eikonal-curvature flow equation with an external force. Such a problem is considered as a model to describe an evolution of height of crystal surface by two-dimensional nucleation or possibly some class of growths by screw dislocations. For applications, it is important to estimate growth rate. Without an external source term the solution only spreads horizontally and does not grow vertically so the source term plays a key role for the growth. Although the large time behavior of parabolic equations are well studied, the equations we study are degenerate parabolic equations where no diffusion effect exists in the normal to each level-set of a solution. Thus, very little is known even for growth rate. Our goal is to describe our recent progress on such type of problems. Ealier results are presented in the paper by H. Mitake, H. A review paper is published in Proc. In this talk, we first show the existence of asymptotic speed called growth rate. We also discuss asymptotic profile as well as estimates on growth rate. Date: Wednesday ; Time: ; Location: building B-8, room 0.

In this talk, we present the local existence and uniqueness of the solutions for the Cauchy problem. This allows consideration of an infinite partial derivative calc horizon control problem. We also give a stability estimate for the shape derivative with respect to the regularization parameter, partial derivative calc, and show the strong convergence of the optimal shapes and the corresponding states for the regularized problem towards a solution to the problem without regularization.

Wolfram Alpha is a great calculator for first, second and third derivatives; derivatives at a point; and partial derivatives. Learn what derivatives are and how Wolfram Alpha calculates them. Enter your queries using plain English. To avoid ambiguous queries, make sure to use parentheses where necessary. Here are some examples illustrating how to ask for a derivative.

Now that we have examined limits and continuity of functions of two variables, we can proceed to study derivatives. Finding derivatives of functions of two variables is the key concept in this chapter, with as many applications in mathematics, science, and engineering as differentiation of single-variable functions. However, we have already seen that limits and continuity of multivariable functions have new issues and require new terminology and ideas to deal with them. This carries over into differentiation as well. When studying derivatives of functions of one variable, we found that one interpretation of the derivative is an instantaneous rate of change of y y as a function of x. This raises two questions right away: How do we adapt Leibniz notation for functions of two variables? Also, what is an interpretation of the derivative?

Firstly, we propose an alternative strategy to the standard fictitious control method: the algebraic solvability is performed and used directly on the adjoint problem. The first part of the talk will be dedicated to a short presentation of practical interest and the characteristic theoretical problems related to these Lagrangian stochastic models while some resolutions to these problems, in simplified situations, will be discussed in the rest of the talk. Models involving branched structures are employed to describe several supply-demand systems such as the structure of the nerves of a leaf, the system of roots of a tree and the nervous or cardiovascular systems. We introduce the so called unfolding operators which we have developed for the problems under study through which we characterize the optimal controls. Smoothness and ellipticity assumptions are sometimes imposed on the energy to improve analytic aspects of associated isoperimetric problems, but these assumptions are not always desirable for some applications nor checkable when the problem comes from a scaling limit. Crouseilles, Splitting methods for Schrödinger equations in rotating frames , in preparation. References J. More precisely, the control is the drift force, localized on a small open subset. As we shall see, both aspects require of an in depth understanding of the dynamics of the systems under consideration. The talk will be devoted to an infinite time horizon linear-quadratic control problem for a stochastic differential equation with additive Rosenblatt noise. The goal of this talk is to present some recent results in [2] concerning the exact controllability of one-dimensional first-order linear hyperbolic systems when all the controls are acting on the same side of the boundary. Fragalà, Bernoulli free boundary problem for the infinity Laplacian , arXiv Assuming sufficient regularity or sparsity , the latter attain high theoretical convergence rates. We consider a finite-difference semi-discrete scheme for the approximation of internal controls of a one-dimensional evolution problem of hyperbolic type involving the spectral fractional Laplacian.

Some open problems and future directions of research will also be presented. References N. Initially, some recent results on stochastic calculus for Rosenblatt and related fractional processes will be presented in the talk. Proske, Stochastic differential equations-some new ideas , Stochastics 79 , Caddick, E. Tempered diffusion equations also termed ''flux-saturated'' or ''flux-limited'' diffusion equations are a class of non-linear versions of the standard diffusion equation displaying a mixture of parabolic and hyperbolic features. There are various methods developed in the last 50 years to understand the mathematical homogenization theory. Besides being algorithmically more efficient if the underlying quadrature rules are nested, this way of performing the sparse tensor product approximation enables the easy use of non-nested and even adaptively refined finite element meshes. Rivas, L. The goal of this talk is to present some recent results in [2] concerning the exact controllability of one-dimensional first-order linear hyperbolic systems when all the controls are acting on the same side of the boundary. We consider an anisotropic variant of a model for atomic nuclei and show that minimizers behave in a fundamentally different way depending on whether or not the energy is smooth and elliptic. The idea extends the standard RBF method by replacing the interpolation in the reconstruction with the least squares fitting approximation.
