What is it about?
We deal with a mathematical description of a solid which grows over time and is elastically deformed. We prove that such a model admits solutions. The growth of the solid can be controlled by providing a nutrient. By assuming this nutrient to diffuse in the body, we are able to prove that the combined growth-diffusion process admits a solution.

Why is it important?
Mechanical systems experiencing growth are common in applications in biological and technological systems. Growth is often influenced by the mechanical state of the solid, calling for the study of both effects. This seems to be a first result in this setting (finite deformations, hyperelasticity, quasistatic equilibria).
