On Geometric Complexity Theory: {M}ultiplicity Obstructions are Stronger than Occurrence Obstructions
Get PDFGeometric Complexity Theory as initiated by Mulmuley and Sohoni in two papers (SIAM J Comput 2001, 2008) aims to separate algebraic complexity classes via representation theoretic multiplicities in coordinate rings of specific group varieties. The papers also conjecture that the vanishing behavior of these multiplicities would be sufficient to separate complexity classes (so-called occurrence obstructions). The existence of such strong occurrence obstructions has been recently disproven in 2016 in two successive papers, Ikenmeyer-Panova (Adv. Math.) and B\"urgisser-Ikenmeyer-Panova (J. AMS). This raises the question whether separating group varieties via representation theoretic multiplicities is stronger than separating them via occurrences. This paper provides for the first time a setting where separating with multiplicities can be achieved, while the separation with occurrences is provably impossible. Our setting is surprisingly simple and natural: We study the variety of products of homogeneous linear forms (the so-called Chow variety) and the variety of polynomials of bounded border Waring rank (i.e. a higher secant variety of the Veronese variety). As a side result we prove a slight generalization of Hermite's reciprocity theorem, which proves Foulkes' conjecture for a new infinite family of cases

A Palearctic species whose adults have been found on Artiodactyla: Bovidae; larvae and nymphs have been collected from Lagomorpha: Leporidae, and Rodentia: Cricetidae, Dipodidae and Muridae. There are no records of Dermacentor ushakovae causing human parasitism.

Liecības, atsaucoties uz citu cilvēku vārdiem: izmantošanas īpatnības pierādīšanā Ukrainas un ārvalstu kriminālprocesos
No full textA. Panova writes about the array of questions related to testimony from the use of other people’s words, formed during the proofing in criminal procedure in Ukraine and other countries. The author has made justifiable conclusions that, according to the norms of Ukrainian criminal procedure, testimonies form the use of other people’s words can be treated as inadmissible, unless parties involved in criminal proceedings agree to use such evidence.A. Panova apraksta jautājumu loku, kas ir saistīts ar liecību, atsaucoties uz citu cilvēku vārdiem, izmantošanas īpatnībām Ukrainas un ārvalstu kriminālprocesos. Autore pamatoti secina, ka atbilstīgi Ukrainas kriminālprocesa tiesību normām liecības, atsaucoties uz citu cilvēku vārdiem, var tikt atzītas par nepieļaujamām, izņemot gadījumus, ja kriminālprocesā iesaistītās puses piekrīt šī pierādījuma izmantošanai

PANOVA Tests and their Application to GNSS Spoofing Detection
No full textAnalysis of variance (ANOVA) is a procedure widely used for detecting differences in the means of samples drawn from different groups. A new class of phase-only ANOVA (PANOVA) tests is derived with the aim of determining if different sample groups are characterized by means with different phases. The application of PANOVA tests to Global Navigation Satellite System (GNSS) spoofing detection is considered, and the
effectiveness of the proposed procedure for characterizing the spatial signature of GNSS signals is shown.JRC.G.6 - Security technology assessmen
