The Fortuin–Kasteleyn polynomial as a bialgebra morphism and applications to the Tutte polynomial
No full textWe compute an explicit formula for the antipode of the double bialgebra of graphs in terms of totally acyclic partial orientations, using some general results on double bialgebras. In analogy to what was already proven in Hopf-algebraic terms for the chromatic polynomial of a graph, we show that the Fortuin–Kasteleyn polynomial (a variant of the Tutte polynomial) is a morphism of the double algebra of graphs into that of polynomials, which generalizes the chromatic polynomial. When specialized at particular values, we give combinatorial interpretations of the Tutte polynomial of a graph, via covering graphs and covering forests, and of the Fortuin–Kasteleyn polynomial, via pairs of vertex-edge colorings. Finally we show that the map associating to a graph all its orientations is a Hopf morphism from the double bialgebra of graphs into the one of oriented graphs, allowing to give interpretations of the Fortuin–Kasteleyn polynomial when computed at negative values. © The copyright of this article is retained by the Author(s)

On the Čakavian dialect of Čunovo near Bratislava
No full textThis article offers a description of a local dialect that belongs to a subarea of Burgenland Croatian (the eastern part of the Haci group of dialects) that has hitherto received little attention. It consists of (a) an analysis of the phonology and phonetics of the dialect, with special attention for the history of the vowel system and the accentuation, (b) remarks on morphology and (c) a number of miscellaneous data that fill in the information missing from the dialectologi-cal maps in the standard work on Burgenland Croatian, viz. Neweklowsky (1978). The conclusion contains a list of the most striking characteristics of the dialect
Secondary imperfectives are primary imperfectives: an empirical investigation of potentially imperfective verbs in Old Church Slavonic
No full textThis chapter discusses two groups of potentially imperfective verbs in Old Church Slavonic: 1) so-called “secondary imperfectives”, i.e. prefixed suffix-derived verbs with prefixed, apparently perfective partners (načinati, načęti ‘begin’), and 2) simplex verbs partnered by prefixed, apparently perfective verbs (pьsati, napьsati ‘write’). The verb pairs are identified by their ability to translate single Greek verb lemmas. The question is explored by comparing the linguistic behaviour of these two groups. Both the tense-mood distribution and the semantics of the verbs are compared. The data show that there are clear distributional differences, where paired prefixed derivates overwhelmingly occur in viewpoint-imperfective and neutral tense-mood forms, while this is much less true for paired simplices, which generally seem more independent of their prefixed partners. The semantic differences between the two types of verbs are more subtle—both types are used to express both continuous and habitual semantics, but paired prefixed derivates seem more likely to be used to describe iterative (actually repeated) events. It therefore seems likely that the paired prefixed derivates were grammaticalised as imperfective first, with a full range of the usual imperfective readings
