• ### Periodic solutions for evolution equations

This article is organized as follows. First we analyze the one dimensional case. Necessary and sucient conditions for the existence and uniqueness of periodic solutions are shown. Results for sub(super)-periodic solutions are proved as well in this case. In the next section we show that the same existence result holds for linear symmetric maximal monotone operators on Hilbert spaces. In the last section the case of non-linear sub-di erential operators is considered.

• ### Factory @ Home: The Emerging Economy of Personal Fabrication

As manufacturing technologies follow the path from factory to home use, like personal computers, “personalized” manufacturing tools will enable consumers, schools and businesses to work and play in new ways. Emerging manufacturing technologies will usher in an industrial “evolution” that combines the best of mass and artisan production models, and has the potential to partially reverse the trend to outsourcing.

In this paper we study periodic solutions of the equation $$\label{a} \frac{1}{i}\left( \frac{\partial}{\partial t}+aA \right)u(x,t)=\nu G (u-f),$$ with conditions $$\label{b} u_{t=0}=u_{t=b}, \,\, \int_X (u(x),1) \, dx =0$$ over a Riemannian manifold $X$, where $$G u(x,t)=\int_Xg(x,y)u(y)dy$$ is an integral operator, $u(x,t)$ is a differential form on $X,$ $A=i(d+\delta)$ is a natural differential operator in $X$. We consider the case when $X$ is a tore $\Pi^2$.
