Thank you very much. I just know some basic concepts about membrane. In theoretical physics and maths, there are some theory about membrane(in string theory or relative theory, I'm not sure). For example, there exist a surface whose area is the smallest surface that bound with a given space curve, is that true? and also the surface tension about the membrane structure. I also know that there are some membrane structures in biology and architecture engineering.
So I want to know what people concerns about membrane and what they have done. How they deal with a membrane structure in physics, and what theory can they have in mathematics.
Again thanks.
