Sommario/riassunto |
|
In Liturgy, Books and Franciscan Identity in Medieval Umbria , Anna Welch explores how Franciscan friars engaged with manuscript production networks operating in Umbria in the late thirteenth and early fourteenth centuries to produce the missals essential to their liturgical lives. A micro-history of Franciscan liturgical activity, this study reassesses methodologies pertinent to manuscript studies and reflects on both the construction of communal identity through ritual |

activity and historiographic trends regarding this process. Welch focuses on manuscripts decorated by the ateliers of the Maestro di Deruta-Salerno (active c. 1280) and Maestro Venturella di Pietro (active c. 1317), in particular the Codex Sancti Paschalis , a missal now owned by the Australian Province of the Order of Friars Minor. |

Sommario/riassunto |
|
If classical Lie groups preserve bilinear vector norms, what Lie groups preserve trilinear, quadrilinear, and higher order invariants? Answering this question from a fresh and original perspective, Predrag Cvitanovic takes the reader on the amazing, four-thousand-diagram journey through the theory of Lie groups. This book is the first to systematically develop, explain, and apply diagrammatic projection operators to construct all semi-simple Lie algebras, both classical and exceptional. The invariant tensors are presented in a somewhat unconventional, but in recent years widely used, "birdtracks" notation inspired by the Feynman diagrams of quantum field theory. Notably, invariant tensor diagrams replace algebraic reasoning in carrying out all group-theoretic computations. The diagrammatic approach is particularly effective in evaluating complicated coefficients and group weights, and revealing symmetries hidden by conventional algebraic or index notations. The book covers most topics needed in applications from this new perspective: permutations, Young projection operators, spinorial representations, Casimir operators, and Dynkin indices. Beyond this well-traveled territory, more exotic vistas open up, such as "negative dimensional" relations between various groups and their representations. The most intriguing result of classifying primitive invariants is the emergence of all exceptional Lie groups in a single family, and the attendant pattern of exceptional and classical Lie groups, the so-called Magic Triangle. Written in a lively and personable style, the book is aimed at researchers and graduate students in theoretical physics and mathematics. |
