This publication is an outgrowth of the actions of the heart for Geometry and Mathematical Physics (CGMP) at Penn nation from 1996 to 1998. the guts used to be created within the arithmetic division at Penn kingdom within the fall of 1996 for the aim of selling and aiding the actions of researchers and scholars in and round geometry and physics on the college. The CGMP brings many viewers to Penn country and has ties with different study teams; it organizes weekly seminars in addition to annual workshops The ebook includes 17 contributed articles on present learn themes in quite a few fields: symplectic geometry, quantization, quantum teams, algebraic geometry, algebraic teams and invariant idea, and personality­ istic periods. many of the 20 authors have talked at Penn nation approximately their learn. Their articles current new effects or talk about attention-grabbing perspec­ tives on fresh paintings. the entire articles were refereed within the typical model of good clinical journals. Symplectic geometry, quantization and quantum teams is one major topic of the e-book. numerous authors research deformation quantization. As­ tashkevich generalizes Karabegov's deformation quantization of Kahler manifolds to symplectic manifolds admitting transverse polarizations, and reviews the instant map on the subject of semisimple coadjoint orbits. Bieliavsky constructs an specific star-product on holonomy reducible sym­ metric coadjoint orbits of an easy Lie team, and he indicates easy methods to con­ struct a star-representation which has fascinating holomorphic properties.

Leonardo da Vinci’s Giant Crossbow

Even if Leonardo’s colossal Crossbow is one in every of his hottest drawings, it's been one of many least understood. "Leonardo’s huge Crossbow" deals the 1st in-depth account of this drawing’s most likely goal and its hugely resolved layout. This interesting e-book has a wealth of technical information regarding the large Crossbow drawing, as it’s a whole examine of this undertaking, notwithstanding this can be as obtainable to the final viewers up to it's also informative with new discoveries for the professors of engineering, expertise and artwork.

Higher Structures in Geometry and Physics: In Honor of Murray Gerstenhaber and Jim Stasheff

This e-book is based round larger algebraic buildings stemming from the paintings of Murray Gerstenhaber and Jim Stasheff which are now ubiquitous in numerous parts of arithmetic— reminiscent of algebra, algebraic topology, differential geometry, algebraic geometry, mathematical physics— and in theoretical physics equivalent to quantum box concept and string thought.

Advances in Robot Kinematics and Computational Geometry

Lately, examine in robotic kinematics has attracted researchers with varied theoretical profiles and backgrounds, comparable to mechanical and electrica! engineering, laptop technology, and arithmetic. It comprises themes and difficulties which are standard for this region and can't simply be met somewhere else. for this reason, a specialized clinical group has built concentrating its curiosity in a wide category of difficulties during this zone and representing a conglomeration of disciplines together with mechanics, idea of structures, algebra, and others.

Singularities in Geometry and Topology. Strasbourg 2009

This quantity arises from the 5th Franco-Japanese Symposium on Singularities, held in Strasbourg in August 2009. The convention introduced jointly a global crew of researchers, typically from France and Japan, engaged on singularities in algebraic geometry, analytic geometry and topology. The convention additionally featured the JSPS discussion board on Singularities and purposes, which aimed to introduce a few contemporary functions of singularity concept to physics and statistics.
