This paper develops a novel tractable overlapping generations (OLG) structure whose aggregate equations resemble model of an infinitely lived representative agent, except that there are no transversality conditions in the OLG economy. The main assumptions complete markets and time-invariant (but age-dependent) consumption shares age-groups. tractability here distinguishes it from conventional m...

We employ a recently developed variant of the functional renormalization group method for spin systems, so-called pseudo Majorana group, to investigate three-dimensional spin-1/2 Heisenberg models at finite temperatures. study unfrustrated and frustrated systems on simple cubic pyrochlore lattices. Comparing our results with other quantum many-body techniques, we demonstrate high quantitative a...
