Dedicated to Anthony Joseph, this quantity includes surveys and invited articles by way of top experts in illustration idea. the point of interest here's on semisimple Lie algebras and quantum teams, the place the impression of Joseph's paintings has been seminal and has replaced the face of the subject.
Two introductory biographical overviews of Joseph's contributions in classical illustration thought (the conception of primitive beliefs in semisimple Lie algebras) and quantized illustration thought (the research of the quantized enveloping algebra) are via sixteen study articles overlaying a couple of diverse and engaging issues in illustration theory.

"How did existence originate and why have been left-handed molecules chosen for its architecture?" this question of excessive public and interdisciplinary medical curiosity is the primary topic of this publication. it truly is widely recognized that during approaches triggering the foundation of existence on the earth, the equivalent prevalence, the parity among left-handed amino acids and their right-handed replicate pictures, used to be violated. The stability was once necessarily tipped to the left – due to which life's proteins this present day solely enforce the left type of amino acids.
Written in an interesting sort, this ebook describes how the elemental construction blocks of existence, the amino acids, shaped. After a understandable creation to stereochemistry, the writer addresses the inherent estate of amino acids in dwelling organisms, specifically the choice for left-handedness. What used to be the reason for the violation of parity of amino acids within the emergence of existence on the earth? the entire interesting types proposed by way of physicists, chemists and biologist are vividly offered together with the medical conflicts. the writer describes the try and be certain any of these versions with the chirality module of the ROSETTA venture, a probe equipped and introduced with the undertaking to land on a comet and examine no matter if there are chiral natural compounds which may were delivered to the Earth by way of cometary impacts.
A actually interdisciplinary astrobiology publication, "Amino Acids and the Asymmetry of existence" will fascinate scholars, researchers and all readers with backgrounds in traditional sciences.
With a foreword by means of Henri B. Kagan.
