In recent years there has been major progress in the classical theory of minimal surfaces. We develop here some of the basic geometric theory and technical tools that have been useful in studying properly embedded minimal surfaces in flat 3-manifolds. A properly embedded surfaceMin a flat 3-manifold ℝ3/Γ, whereΓ⊂Iso(ℝ3) acts freely and properly discontinuously on ℝ3, lifts to aΓ-periodic surfacein ℝ3. Up to taking finite index subgroups ofΓ, we may assume that eitherΓis a lattice in ℝ3(triply-periodic),Γis a lattice in ℝ2⊂ℝ3(doubly-periodic), orΓis the cyclic group generated by a screw motion symmetrySθof ℝ3with axis thex3-axis and rotation angle θ (singlyperiodic).In section 1 we discuss the maximum principle at infinity for proper minimal surfaces and applications. In section 2 we briefly go over the Geometric Dehn’s Lemma and related barrier constructions. In sections 3, 4, and 5 we cover the basic theories of triply, doubly, and singly periodic minimal surfaces. In section 6 we go over some of the very recent work on the topology and asymptotic geometry of properly embedded minimal surfaces in ℝ3.
