Swimming lessons for microbots — •Joseph Avron — Department of Physics, Technion, Haifa, Israel

Swimming at low Reynolds number is geometric. A gauge theory of swimming due to Wilczek and Shapere, and going back to the 80’s, shall be described with an eye on its implications to the swimming of micron size robots (microbots). The optimization problem associated to microbot swimming shall be formulated. In two dimensions one can use conformal methods to find explicit solutions and illustrate the optimal strokes of few swimming styles.
