Casimir energy inside a triangle
For certain class of triangles (with angles proportional to \fr{\pi}{N},
) we formulate image method by making use of the group generated
by reflections with respect to the three lines which form the triangle under
consideration. We formulate the renormalization procedure by classification of
subgroups of and corresponding fixed points in the triangle. We also
calculate Casimir energy for such geometries, for scalar massless fields. More
detailed calculation is given for odd .Comment: Latex, 13 page
Quantum mechanical effects of topological origin
Following a brief review of the original Casimir and Aharonov-Bohm effects, some other effects of similar natures are mentioned. A Casimir interaction between AB fluxes is presented. Possible realizations of the Casimir effects for massive charged fields in solid state structures and a new AB effect for photons are suggested
