Bose-Einstein condensation has been realized in dilute atomic vapors. Thisachievement has generated immerse interest in this field. Presented is a reviewof recent theoretical research into the properties of trapped dilute-gasBose-Einstein condensates. Among them, stability of Bose-Einstein condensatesconfined in traps is mainly discussed. Static properties of the ground stateare investigated by use of the variational method. The anlysis is extended tothe stability of two-component condensates. Time-development of the condensateis well-described by the Gross-Pitaevskii equation which is known in nonlinearphysics as the nonlinear Schr\"odinger equation. For the case that theinter-atomic potential is effectively attractive, a singularity of the solutionemerges in a finite time. This phenomenon which we call collapse explains theupper bound for the number of atoms in such condensates under traps.Comment: 74 pages with 12 figures, submitted to the review section of  International Journal of Modern Physics
