Query: Structure of social relations in the novel \emph{The Master and
  Margarita} by~M.~A.~Bulgakov: A network analysis of verbal communications   A network analysis of the structure of social relationships in one of the
most popular Russian novels of the Soviet era \emph{The Master and Margarita}
by M.~A.~Bulgakov has been carried out. The structure of the novel is complex,
i.e., there is `a story within a story'. In our study, only paired verbal
communications (conversations) between explicitly present and acting characters
have been taken into account; frontal communications, monologues, off-stage
characters as well as expected connections between characters have not been
assessed. Based on a character pair verbal communication matrix, a graph has
been constructed, the vertices of which are the characters of the novel, while
the edges correspond to the connections between them. Taking only dialog into
account leads to the result, that the social network can be described by an
ordinary, rather than a directed graph. Since the activity of the dialogs was
out of our intended scope, the edges have been given no weights. The largest
connected component of the graph consists of 76 characters. Centralities, such
as degree, betweenness, closeness, eigenvector, and assortativity coefficient
were computed to characterize the network. The assortativity coefficient of the
network under consideration is negative $-0.133$, i.e., the network
demonstrates the properties of an artificial network. The structure of the
communities in the network was also analysed. In addition to the obvious large
communities~ -- the characters from the Yershalaim part of the novel and the
characters of the Moscow part -- the analysis also revealed a fine structure in
the Moscow component. Using the analysis of centralities, a group of main
characters has been detected. The central characters of the novel are Bezdomny,
Woland, Levi Matthew, Koroviev, Azazello, Behemoth, Bosoi, Warenukha, Master,
and Margarita.
