THANKS TO ALL AUTHORS THAT PARTICIPATED IN THE PROCESS.

Dear

 Mathematical Ecology Community

 As can you see in http://ams2010.somachi.cl, the American Mathematical Society (AMS) and the Sociedad de Matemática de Chile (SOMACHI) will be holding their first joint meeting in Pucon, Chile December 15-18, 2010. A special session on

 Applications of Differential and Difference Equations in Biology and Ecology (Code: SS 10A)

to be held at this meeting. I anticipate that our special session will be held over one or two days of the four-day meeting, with a length of up to two blocks, for a total of 12 talks (it's quality we're after, not quantity) of 20-minute followed by 10-minute breaks. Some of the speakers at this special sessions are by invitation, but are welcome who may submit talks on their own, especially creative ideas from younger mathematicians. We would welcome to an open problem session proposal.

The first deadline for abstracts is June 4, 2010 (for those interested in an early response) and the second deadline is September 10, 2010. All participants at the session are expected to register for the meeting and to pay the registration fee.

All speakers, including invites by organizers, must submit abstracts. Talks without abstracts will not be scheduled.

Please download the template

SPECIAL SESSION

APLICATIONS OF DIFFERENTIAL AND   DIFFERENCE EQUATION IN BIOLOGY AND ECOLOGY

December 15 to 18, 2010, Pucón-Chile

 It has been said that the applcation of mathematics in the field of biology in the 20th and 21st centuries is as revolutionary a tool for biologists as was the development and application of the microscope to biology in the 16th and 17th centuries. In the past thirty years differential and difference equations and the theory of dynamical systems have been applied to ecology, epidemiology, population genetics, neurobiology and various problems in physiology with outstanding results. For instance, mathematicians and biologists have used diference equations to study the demographics of cultures of our beetles and to predict and subsequently observe the onset of period doubling and chaotic phenomena in laboratory experiments. Others have used differential equation models to understand phenomena such as the spread of AIDS, influenza, and other diseases. This special session will bring together researchers from North and South America and provide them with the opportunity to collaborate and to determine future directions for the applications of differential and difference equations to biology and ecology.

Note: Michael Mackey (McGill University, Centre for Applied Mathematics in Biosciencie Medicine and current president of the Society for Mathematical Biology) endorses this session in mathematical biology for the conference. This session is also sponsored by the Chilean Group of Mathematical Ecology.

TITULO: Stability loss delay in dynamic transcritical bifurcations. Application in slow-fast biological models. 

Miércoles 13 de enero 2010, a las 17:00 hrs, Sala de Seminarios CMM, séptimo piso.

Resumen: In most applications the dynamics of different variables of a system of ordinary differential equations are hierarchically scaled. Properties of such systems, called slow-fast systems, can be studied by using singular perturbation theory. We present some classical results of the theory: Tikhonov's theorry, center manifold reduction, and the canards, which are special trajectories of slow-fast systems that first move near the stable part of the slow manifold, then move near the unstable part of it. We consider the case where the fast dynamics exhibit transcritical bifurcations and we study the canard solutions and the corresponding stability loss delay phenomenon.  We compute the entrance-exit functions in the vicinity of the canards. We give appllications to a class of biological models describing the competition of species on substrates.
