Abstract. This paper studies both nonautonomous stochastic differential equations and stochastic differential delay equations with Markovian switching. A new result on almost sure stability of stochastic differential equations is given. Moreover, we provide new conditions for tightness and almost su[r]
ABSTRACT. Starting from the Einstein equation in general relativity, we carefully derive the Einstein constraint equations which specify initial data for the Cauchy problem for the Einstein equation. Then we show how to use the conformal method to study these constraint equations.
The department uses a range of tests (andbackground information) to determine an enteringstudent’s mathematical preparation and “readiness” toattempt courses at the basic, precalculus or calculuslevels. Mathematics placement examinations areadministered at conveniently scheduled hours on anum[r]

The goal of these notes is to explain recent results in the theory of complex varieties, mainly projective algebraic ones, through a few geometric questions pertaining to hyperbolicity in the sense of Kobayashi. A complex space X is said to be hyperbolic if analytic disks f : D → X through a given p[r]

Mistakes in the use of articlesESL students make several mistakes while writing English. Interestingly, most of these mistakes are not all thatserious and can be avoided easily. Here is a quick overview of common mistakes in the use of articles[r]
This paper deals with the problem of global exponential stabilization for a class of nonautonomous cellular neural networks with timevarying delays. The system under consideration is subject to timevarying coefficients and timevaying delays. Two cases of timevarying delays are considered: (i) the de[r]

We study the strong rate of convergence of the tamed EulerMaruyama approximation for onedimensional stochastic differential equations with superlinearly growing drift and H¨older continuous diffusion coef ficients.
The infinite system of differential equations for the nonequilibrium Green functions of electrons in a single-level quantum dot connected with two conducting leads is truncated by applying the mean-field approximation to the mean values of the products of four operators.

We find upper bounds for the rate of convergence when the EulerMaruyama approximation is used in order to compute the expectation of nonsmooth functionals of some stochastic differential equations whose diffusion coefficient is constant, whereas the drift coefficient may be very irregular.

We consider a class of stochastic functional differential equations with distributed delays whose coefficients are superlinear growth and H¨older continuous with respect to the delay components. We introduce an EulerMaruyama approximation scheme for these equations and study their strong rate of con[r]
The notions of equivalence and strict equivalence for order one differential equations of the form f(y 0 , y,z) = 0 are introduced. The more explicit notion of strict equivalence is applied to examples and questions concerning autonomous equations and equations having the Painleve property. The ´ or[r]
