around the roots of plants, as Nicole van Dam and Harro Bouwmeester report in a review of this fi eld (Trends Plant Sci. (2016) DOI: http://dx.doi. org/10.1016/j.tplants.2016.01.008). Direct investigation of signalling in the rhizosphere is currently focused on communication between plants and their microbial symbionts, as Vittorio Venturi and Christopher Keel report, although the scope could b...

Gordon Holmes Lecture: Gordon Holmes and the neurological heritage.

Sir Gordon Holmes is one of the great figures in the history of twentienth century neurology. In him, there came together the traditions of German and British neurology which moulded a physiological approach to normal and disordered function of the nervous system with a commitment to interpreting clinical phenomena in the light of meticulous pathological examination. He, more than any other ind...

Noncommutative Sine-gordon Model Extremizing the Sine-gordon Action

As I briefly review, the sine-Gordon model may be obtained by dimensional and algebraic reduction from 2+2 dimensional self-dual U(2) Yang-Mills through a 2+1 dimensional integrable U(2) sigma model. I argue that the noncommutative (Moyal) deformation of this procedure should relax the algebraic reduction from U(2) → U(1) to U(2) → U(1)×U(1). The result are novel noncommutative sine-Gordon equa...
