"A Categorical View of Completeness in DiUniform Texture Spaces" Abstract In the previous studies, it was shown that the ditopological texture spaces provide a unified setting for the study of topology, bitopology and fuzzy topology on Hutton algebras. Following that, a suitable uniformity theory in textures was constructed under the name diuniformity, and this represented a generalization of classical quasiuniformity. Therefore, by defining regular Cauchy difilters on a texture, the concept of dicompleteness as a natural counterpart of "completeness" in the sense of quasiuniformity has been introduced for diuniform texture spaces. Accordingly, in this work the following ideas will be taken up

"Quasi Lattices" Abstract Under certain conditions there are considerably more quasilattices than Banach lattices. For example, (within reason) nearly every finite dimensional ordered Banach space is a quasilattice, while there is essentially only one ndimensional Banach lattice for each n. We will show how certain properties carry over from Banach lattices to quasilattices and discuss some still open problems. (Technical details are kept to a minimum, the talk should be accessible to students and nonanalysts who know what a Banach space is).

"High Order Finite Difference Approximations of Multiphysics Problems" Abstract
Great progress has been made for high order finite difference methods during the last 20 years. It is now rather straightforward to construct stable and high order accurate multiblock finite difference schemes in a buildingblocklike manner. In this talk we will discus new developments, new extensions, new fields of applications, share experience on the full scale use of the technique, and speculate about future trends. We present the theory by using simple model problems, and exemplify with complex multiphysics applications. First we walk through the basic technique for a simple model problem where all the ingredients such as wellposedness, summationbyparts operators, penalty techniques for boundary and interface conditions, and the energy method are explained. Next, we discuss the application of the theory to coupling techniques for conjugate heat transfer, earthquake simulations, fluid solid interaction and simulation of potential propagation in neuronal branches. Finally we discuss new timeintegration procedures, new boundary conditions for the NavierStokes equations and a new variance reduction technique for stochastic partial differential equations.

Stochastic Equations in Physics and Biology" Abstract: I will give a very brief introduction into the framework of stochastic calculus, followed by a couple of examples borrowed from physics and biology. The first example is related to the transport of colloids through narrow nanochannels, the second example is concerned with the motion of the selfpropelled particles, such as bacteria.
