Sole, E. Engelbrecht and E. Brand, (NCA 2019/605). Etymology: The specific epithet is patronym in honour of Finn Robert Pirk the son of the third author, who loves all creepy crawlies. Diagnosis: The males of S. finni sp. nov. are distinguishable from other members of the genus occurring in the Karoo based on the following combination of characters.

Schurian-finiteness of blocks of type Hecke algebras
No full textFor any algebra over an algebraically closed field , we say
that an -module is Schurian if . We
say that is Schurian-finite if there are only finitely many isomorphism
classes of Schurian -modules, and Schurian-infinite otherwise. By work of
Demonet, Iyama and Jasso it is known that Schurian-finiteness is equivalent to
-tilting-finiteness, so that we may draw on a wealth of known results in
the subject. We prove that for the type Hecke algebras with quantum
characteristic , all blocks of weight at least are
Schurian-infinite in any characteristic. Weight and blocks are known by
results of Erdmann and Nakano to be representation finite, and are therefore
Schurian-finite. This means that blocks of type Hecke algebras (when ) are Schurian-infinite if and only if they have wild representation type if
and only if the module category has finitely many wide subcategories. Along the
way, we also prove a graded version of the Scopes equivalence, which is likely
to be of independent interest.Comment: 40 pages. v4 combines the paper with its sequel arXiv:2208.05711 by

A model for energy pricing with stochastic emission costs
No full textData source: Figures and tables, https://doi.org/10.1016/j.eneco.2009.11.001
Link to a related website: https://prism.ucalgary.ca/bitstream/1880/48998/1/Elliott_Model_Energy_2009_postprint_file.pdf, Open Access via UnpaywallWe use a supply-demand approach to value energy products exposed to emission cost uncertainty. We find closed form solutions for a number of popularly traded energy derivatives such as: forwards, European call options written on spot prices and European Call options written on forward contracts. Our modeling approach is to first construct noisy supply and demand processes and then equate them to find an equilibrium price. This approach is very general while still allowing for sensitivity analysis within a valuation setting. Our assumption is that, in the presence of emission costs, traditional supply growth will slow down causing output prices of energy products to become more costly over time. However, emission costs do not immediately cause output price appreciation, but instead expose individual projects, particularly those with high emission outputs, to much more extreme risks through the cost side of their profit stream. Our results have implications for hedging and pricing for producers operating in areas facing a stochastic emission cost environment.Robert J. Elliott, Matthew R. Lyle and Hong Mia
