The 1/x 2 deformed c = 1 matrix model is studied at finite radius and nonzero cosmological constant. Calculational techniques are presented and illustrated in some examples. Furthermore, a new kind of R → 1/R duality is discovered, which mixes different genera. CERN-TH.7021/93 Recently the 1/x 2

spin polarization operators. The spin structure of the solution is completely fixed independently of the radial distribution of the magnetic field which influences only the radial modes. We solve explicitly the radial equations for the uniform magnetic field inside a solenoid of a finite radius

The axisymmetric boundary layer on a fixed circular disc of radius a due to a rotating fluid has been examined numerically. A series expansion solution, starting at the outer edge of the disc, is found to match the similarity solution due to Bodewadt at r = \a. Numerical solutions, obtained

properties for the radius of comparison which strengthen its analogy with covering dimension for commutative spaces. We then give several applications of these results. New examples of C∗-algebras with finite radius of comparison are given, and the question of when the Cuntz classes of finitely generated

Abstract. Migrating cells measure the external environment through receptorbinding of specific chemicals at their outer cell membrane. In this paper this non-local sampling is incorporated into a chemotactic model. The existence of global bounded solutions of the non-local model is proven for bounded and unbounded domains in any space dimension. According to a recent classification of spikes and plateaus, it is shown that steady state solutions cannot be of spike-type. Finally, numerical simulations support the theoretical results, illustrating the ability of the model to give rise to pattern formation. Some biologically relevant extensions of the model are also considered.
