*Dr. Patrick Wahlberg - Newcastle*

A transformation of almost periodic pseudodifferential operators to Fourier multiplier operators on vector-valued functions.

*Dr. Alessandro Ottazzi - Universita di Genova*

We are interested in contact mappings on nilpotent stratified Lie groups G (Carnot groups). If the group of contact mappings is infinite dimensional, we say that G is nonrigid, whereas we say that G...

*Dr. Chris Meaney - Macquarie*

Salem's proof of the Rademacher-Menshov Theorem shows that one constant works for all orthogonal expansions in all L2-spaces. By changing the emphasis in Salem's proof we produce a lower bound for...

*Dr. Andrew Hassell - ANU*

Consider the time-dependent Schrodinger equation on a complete noncompact Riemannian manifold M (for example, a manifold which looks like flat Euclidean space outside a compact set). This PDE has a...

*Dr. Raed Raffoul - UNSW*

We use the Nelson algebra of operants, a construction generalising the symmetric algebra of a vector space which, in the setting of commutative Banach algebras, respects spectral theory in a very...

*Dr. Sergey Ajiev - UNSW*

The boundedness properties of the generalized Sobolev derivatives as operators in the anisotropic classes of Besov and Lizorkin-Triebel spaces of vector-valued functions with the mixed Lebesgue norm...

*Prof. Sergey Neshveyev - University of Oslo*

The spectrum of the center of an algebra can sometimes be interpreted as a boundary of a random walk, which is convenient for computations. It turns out that the algebra itself can often be...

*Dr. Quoc Thong Le Gia - UNSW*

Approximation of pseudo-differential equations on the sphere using collocation Pseudo-differential equations on the unit sphere play an important role in geo-sciences, oceanography, and meteorology....

*Dr. Sergey Ajiev - UNSW*

Traditional approximation properties of anisotropic Besov and Lizorkin-Triebel spaces of vector-valued functions defined on an Euclidean space are studied.We construct certain wavelet X-bases...

*Prof. James Byrnes - Prometheus Inc.*

A question which naturally arises in both pure and applied mathematical analysis is: How close to constant can the modulus of a polynomial be on the unit circle if the coefficients of the polynomial...
