Wegner-Houghton equation in low dimensions

We consider scalar field theories in dimensions lower than four in the context of the Wegner-Houghton renormalization group equations (WHRG). The renormalized trajectory makes a non-perturbative interpolation between the ultraviolet and the infrared scaling regimes. Strong indication is found that in two dimensions and below the models with polynomial interaction are always non-perturbative in ...

Harvard University

The comments I offer in this memorandum on the MAC’s recommendations are limited to the issues listed below. In many cases, I agree with the MAC’s recommendations, and offer comments in order to contribute to broader debates about climate policy design in California, which will continue for years to come. There are also instances where I disagree with the MAC’s conclusions or believe the MAC fa...

Nearly all economic models of the household have implications for how characteristics of the children in a family affect human capital investments in their siblings. Much evidence suggests that perceived returns to investing in sons is higher than investing in daughters in many economies (often due to cultural practices rather than inherent productivity differences). When this is so – and where...
