By Larry C. Grove

``Classical groups'', named so by way of Hermann Weyl, are teams of matrices or quotients of matrix teams via small common subgroups. hence the tale starts off, as Weyl recommended, with ``Her All-embracing Majesty'', the final linear team $GL_n(V)$ of all invertible linear variations of a vector area $V$ over a box $F$. All extra teams mentioned are both subgroups of $GL_n(V)$ or heavily similar quotient teams. many of the classical teams encompass invertible linear alterations that recognize a bilinear shape having a few geometric importance, e.g., a quadratic shape, a symplectic shape, and so forth. therefore, the writer develops the necessary geometric notions, albeit from an algebraic viewpoint, because the finish effects may still observe to vector areas over more-or-less arbitrary fields, finite or countless. The classical teams have proved to be very important in a wide selection of venues, starting from physics to geometry and much past. in recent times, they've got performed a sought after function within the class of the finite easy teams. this article offers a unmarried resource for the elemental evidence concerning the classical teams and in addition comprises the necessary geometrical history details from the 1st rules. it really is meant for graduate scholars who've accomplished normal classes in linear algebra and summary algebra. the writer, L. C. Grove, is a well known specialist who has released commonly within the topic zone.
