Linearization of an abstract convexity space [PDF]
, 1978 Axiomatic convexity space, introduced by Kay and Womble [22] , will be the main topic discussed in this thesis. An axiomatic convexity space (X,C), which is domain finite and has regular straight segments, is called a basic convexity space, A weak ...

Risk capital allocation for RORAC optimization
, 2011 This paper considers the financial optimization problem of a firm with several sub-businesses striving for its optimal RORAC. An insightful example shows that the implementation of classical gradient capital allocation can be suboptimal if division ...

Precautionary Saving against Correlation under Risk and Ambiguitya
Journal of Money, Credit and Banking, EarlyView.Abstract This paper considers precautionary saving against the correlation between two risky attributes (wealth and health) and investigates how the correlation affects optimal savings under multivariate preferences. The signs of higher‐order cross‐derivatives play a key role in determining the direction of precautionary saving against such correlation.

Mathematical Finance, EarlyView.ABSTRACT We study a dynamic portfolio optimization problem under the mean–variance–variance (M‐V‐V) criterion proposed by Maccheroni et al. It is an analogue of the Arrow–Pratt approximation to the well‐known smooth ambiguity model. Under the standard Black–Scholes framework, we derive fully explicit equilibrium investment strategies in which a DM's ...

Taking Risks, With and Without Probabilities
Noûs, EarlyView.ABSTRACT Some hold that expected utility is too restrictive in the way it handles risk. Risk‐weighted expected utility is an alternative that allows decision‐makers to have a range of attitudes toward probabilistic risk. It holds that any attitude within this range is instrumentally rational, since these attitudes represent different, equally good ...

Generalized minimizers of convex integral functionals, Bregman distance, Pythagorean identities [PDF]
, 2001 summary:Integral functionals based on convex normal integrands are minimized subject to finitely many moment constraints. The integrands are finite on the positive and infinite on the negative numbers, strictly convex but not necessarily differentiable ...

Combining phenomic and genomic selection for pea breeding improvement
The Plant Phenome Journal, Volume 9, Issue 1, December 2026.Abstract Pea (Pisum sativum L.) is a strategic crop in the development of sustainable agriculture. However, the genetic gain remains limited despite advances in breeding. Genomic selection holds promise to accelerate varietal improvement, but its high implementation cost restricts its use in crops.

Journal of Multi-Criteria Decision Analysis, Volume 33, Issue 2, August 2026.ABSTRACT The Flexible and Interactive Tradeoff Elicitation (FITradeoff) method is a Multi‐Attribute Decision‐Making (MADM) approach designed to capture the preferences of a Decision Maker (DM) while minimising cognitive effort. To reduce the frequency of interactions and optimise the preference elicitation process, this paper introduces an innovative ...

Theoretical Economics, Volume 21, Issue 2, Page 373-401, May 2026.Models of stochastic choice typically use conditional choice probabilities given menus as the primitive for analysis, but in the field these are often hard to observe. We consider the case where an analyst has access to a marginal stochastic choice dataset containing the marginal distributions of available menus and of choices, but not to conditional ...

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.
