In 1997 he was appointed as The Benson Ford Professor of Applied Mathematics at University College Cork (Ireland). From 2000 till present, VIS has been a Professor of Applied Mathematics at Keele University (UK). Since 1993 he had a string of Visiting Professorships, most frequently at the universities of Aix-Marseille and Toulon. Since 1994 he has been an editor of Nonlinear Processes in Geophysics. He has supervised a substantial number of PhD and MSc students and PostDocs, who remained at academia as active researchers. He  published more than 100 papers on various aspects of nonlinear dynamics in the context of environmental flows.  The main research accomplishments include:

·         A weakly nonlinear theory of self-interaction of internal gravity waves in the ocean, which, inter alia, predicts a possibility of collapses of 3D wave packets.

·         A novel asymptotic approach for describing nonlinear dynamics of finite amplitude long-wave perturbations in shear flows which enables a rigorous  derivation of a wide class of novel (1+1)D and (2+1)D nonlinear evolution equations with nonlocal dispersion,  the (2+1)D equations describe collapses, the  self-focussing of the perturbations results in formation of point singularities in finite time.

·         Major contributions into theory of wind waves on shear flows, in particular, found a novel class of surface solitary waves existing due to vertical shear, developed (with A.Slunyyaev) a paradigm changing approach towards nonlinear dynamics of waves on jet currents, which led to the discovery of robust strongly nonlinear long-lived envelope solitary waves. These waves might explain the observed prevalence of rogue waves on jet currents.

·          A very efficient novel numerical approach for phase resolving simulations of 3-D water wave dynamics based on the reduced Zakharov integro-differential equation (jointly with S. Annenkov) which enabled us  to tackle hitherto unthinkable simulations of deterministic and random wave field dynamics, in particular:

(i)                  to find the limits of predictability of deterministic description of water waves dynamics;

(ii)                 to verify the kinetic theory for water waves, to find the range of its applicability and  identify the mechanism responsible for the discrepancy between the kinetic theory predictions and fieald observations.

·         Theoretically predicted and then found in oceanic observations a novel type of waves  occurring due to the `non-traditional' component of the Earth's rotation.

·         Made significant contribution to statistical theory of nonlinear water waves. In particular, jointly with S.Annenkov,

(i)                  revealed the fundamental role of near-resonant interactions in evolution of nonlinear random wave fields;

(ii)                derived the `Generalised Kinetic Equation' (GKE) and implemented it in various contexts  

(iii)              described long-term evolution of skewness and kurtosis which enables to find probability of rogue waves from first princciples;

(iv)              have shown that it is small but finite non-Gaussianty that at large times results in the order one discrepancy in shape of the wave spectra between the observations and predictions based on the kinetic equation.

 

 

Vakhtang Putkaradze received his PhD from the University of Copenhagen, Denmark, and held faculty positions in New Mexico, Colorado State University, and, most recently, at the University of Alberta, where he was a Centennial Professor between 2012-2019. From 2019 to 2022, he led the science and tech part of the Transformation Team at ATCO Ltd, first as a Senior Director and then Vice-President. He has developed new mathematical tools for variational methods coupled with ideas from symmetry and geometry to various practical problems significant for applications. The techniques are particularly beneficial for problems with several interacting counterparts where deriving dynamics from first principles is challenging, such as fluid-structure interactions,  dynamics of porous media, molecular dynamics of polymers involving electrostatic and elastic interactions, and applications of the theory of optimal control to problems such as rolling robots. He has received numerous prizes and awards for research and teaching, including Humboldt Fellowship, Senior JSPS fellowship, Flaherty Visiting Professorship, and CAIMS-Fields industrial math prize.

V. Afraimovich Award

(Edson Denis Leonel)

 

​Edson Denis Leonel I present some of my main contributions to understanding phase transitions in nonlinear dynamical systems. It is known in the literature that at a second-order phase transition, also called a continuous phase transition, the dynamical variable identifying the order parameter approaches zero continuously. In contrast, the susceptibility of the order parameter diverges. Near a phase transition, the observables characterizing the dynamics are described by power laws leading the dynamics to be scaling invariant. Examples include Lyapunov exponents, diffusion coefficient, quadratic mean velocity, periodic structures in the parameter plane producing objects called shrimps, distance from the attractor, chaotic transient, and the attractor itself, either regular or chaotic, among many others. When such measurable quantities are also scaling invariant, generally made via a control parameter or change in the initial condition, one can find a set of critical exponents that describe the dynamics of the observable by using scaling transformations. The central phenomenology to describe this property uses a set of scaling hypotheses and a generalized homogeneous function. From them, we find an analytic relation for the exponents leading to a scaling law. Indeed, scaling laws are helpful in the characterization and definition of universality classes and can be proved using numerical simulations or analytic descriptions. All of the above have been applied in numerous problems in nonlinear dynamics by myself. 
My original contribution's breakthrough characterized a continuous phase transition in some chaotic systems. We focused on answering a set of four main questions:
1. Identify the broken symmetry.
2. Define the order parameter.
3. Discuss the elementary excitation.
4. Discuss the topological defects that impact the transport of particles.
Two main classes of problems were investigated: (i) conservative dynamics, whose time evolution is described by two-dimensional, nonlinear, and area-preserving mappings for the action and angle variable. The intensity of the nonlinearity given by a periodic function is made by a control parameter controlling a transition from integrability to non-integrability; (ii) dissipative systems whose transitions involve suppression of unlimited diffusion of the action variable that also includes a class of more complicated systems such as time-dependent dissipative billiards. In case (i), the own control parameter defines the elementary excitation. The topological defects are linked to periodic structures in the phase space leading the dynamics to experience stickiness. In case (ii), the topological defects are linked to attracting periodic orbits, which depend on the own control parameters. The elementary excitation also relies on the strength of the nonlinearity. The order parameter in both cases is related to the diffusion limit of the dynamical observable, which is closely related to the control parameters and approaches zero at the transition. At the same time, its susceptibility diverges at the same limit. Moreover, there is an algebraic break of symmetry in the two transitions.
