An Entrepreneur’s Problem Under Perfect Foresight Consider a firm characterized by the following: kt Firm’s capital stock at the beginning of period t f(k) The firm’s total output depends only on k it Investment in period t j(i, k) AdJustment costs associated with investment i given capital k ξt = it + jt eXpenditures (purchases plus adjustment costs) on investment β = 1/R Discount factor for f...

A bstract We consider the issue of information recovery for an object carrying energy and entropy into a black hole using generalized formalism, in context JT gravity where backreaction problem can be solved exactly. verify main aspects Hayden-Preskill scenario but with some refinements. show that is encoded Hawking radiation redundant way, as expected quantum error correcting code. how extrema...

We present a JT gravity set up that reveals the evidence of (Euclidean) wormhole to black hole phase transition at finite charge density and/or chemical potential. identify low temperature system as charged solution. As is increased, it undergoes first order two density. At critical point (T=T0) transition, both Free energy (density) and discontinuous change. Finally, we conjectured field theor...

The term ‘Just Transition’ (JT) emerged from the 1970s North American labour movement to become a campaign for planned energy transition that includes justice and fairness workers. There is diversity in JT narratives ambitions different actors put forward regarding its aims strategies. This article critically reviews academic grey literature on Global South Africa examine how labour, advocacy, ...

We consider Minkowskian Jackiw-Teitelboim (JT) gravity in Bondi gauge at finite temperature, with non-zero vacuum energy. Its asymptotic symmetries span an extension of the warped Virasoro group, dubbed "BMS$_2$", which we investigate detail. In particular, show that this has a single coadjoint orbit when central charges are real and non-zero. The ensuing BMS-Schwarzian action no saddle points,...

This study assessed the relationships of job tasks and living conditions with occupational injuries among coal miners. The sample included randomly selected 516 underground workers. They completed a standardized self-administred questionnaire. The data were analyzed via logistic regression method. The rate of injuries in the past two years was 29.8%. The job tasks with significant crude relativ...
