We propose firm-level measures of exposures to macroeconomic risks that substantially
improve out-of-sample robustness compared to standard estimation approaches. Systematic …

The authors construct ESG strategies that have been shown to outperform in popular articles.
They assess performance benefits to investors when accounting for sector and factor …

There is a consensus that equity factors are cyclical and depend on macroeconomic
conditions. To build well-diversified portfolios of factors, one needs to account for the fact that …

In this article, the authors compare different approaches for constructing multifactor equity
portfolios: bottom-up score-weighting approaches that target high-factor intensity and top-…

The finance literature has established a size effect: stocks with small market capitalization
outperform larger stocks over the long term. The size factor is included in asset-pricing models …

Scale invariant presentation of inclusive spectra in terms of light front variables is proposed.
The variables introduced go over to the well-known scaling variables $x_F = 2 p_z /\sqrt s$ …

… if M + ∆M < 0.4 GeV or M − ∆M > 0.4 GeV, respectively. Fulfillment of the condition M +∆M <
… fulfillment of the condition M − ∆M > 0.7 GeV implies the emergence of the K0 + π0 system. …

… We discuss the celebrated Blok-Esakia theorem on the isomorphism between the lattices of
extensions of … We only note here that a least element does exist if \(M\) is a subframe logic. …

… lattices, and Esakia duality for Heyting … Esakia’s lemma and its generalisation as obtained
in our paper [22] with Bjarni Jónsson. Finally, in Sect. 2.6, we derive both Priestley and Esakia …

… We prove that the Blok-Esakia isomorphism for universal preserves and reflects strong
structural and universal completenesses. For (quasi)-varieties strong versions are equivalent to …
