Small complete caps in PG(4n + 1, q)

In this paper we prove the existence of a complete cap of (Formula presented.) of size (Formula presented.), for each prime power (Formula presented.). It is obtained by projecting two disjoint Veronese varieties of (Formula presented.) from a suitable (Formula presented.) -dimensional projective space. This shows that the trivial lower bound for the size of the smallest complete cap of (Formula presented.) is essentially sharp

Macroprudential stress-testing practices of central banks in Central and Southeastern Europe: comparison and challenges ahead

This paper reviews and compares stress-testing practices of central banks in Central and Southeastern Europe (CSEECBs) and outlines challenges in the area of stress testing going forward. The authors, focusing their comparison on CSEECBs, construct the baseline and stress scenarios, map macroeconomic scenarios and microeconomic factors to risk factors, calculate risk exposures to different risk indicators, and estimate outcome indicators to inform macroprudential policy. The main challenges going forward concern data reliability, consideration of quantitative microprudential indicators, incorporation of feedback effects in stress tests, institutionalization of macroprudential policy responses to alarming stress-test results, and information exchange for better cross-border supervision.Web of Science48414311
