The idea of elation generalized quadrangle is a normal generalization to the idea of generalized quadrangles of the real suggestion of translation planes within the conception of projective planes. virtually any recognized category of finite generalized quadrangles could be produced from an appropriate type of elation quadrangles.

In this booklet the writer considers numerous features of the speculation of elation generalized quadrangles. detailed awareness is given to neighborhood Moufang stipulations at the foundational point, exploring for example a query of Knarr from the Nineteen Nineties about the very thought of elation quadrangles. all of the recognized effects on Kantor’s top energy conjecture for finite elation quadrangles are amassed, a few of them released the following for the 1st time. The structural thought of elation quadrangles and their teams is seriously emphasised. different similar themes, resembling p-modular cohomology, Heisenberg teams and life difficulties for yes translation nets, are in short touched.

The textual content begins from scratch and is basically self-contained. many different proofs are given for recognized theorems. Containing dozens of routines at quite a few degrees, from really easy to particularly tough, this path will stimulate undergraduate and graduate scholars to go into the interesting and wealthy international of elation quadrangles. The extra finished mathematician will specially locate the ultimate chapters hard.
