The book entitled with "Complex Manifolds and its submanifolds" deals with the properties of quarter symmetric non metric connection in a nearly kaehler manifold, generalized CR-submanifolds of quasi kaehler manifolds. The integrability conditions of the distribution involved in the definition of such manifolds. Geometry of leaves of such distributions are also given and almost Hermitian manifold equipped with semi symmetric non metric connections. The properties of a contravarient almost analytic vector field with semi symmetric non metric connection are also given.

Biometrics, the word not only generates a spark of interest but it is also an important aspect to trace human expressions. Signature, an expression of this kind portrays a uniqueness which can be captured thus it becomes vital. Signature is a mark of authenticity which can be tampered by observing carefully. Dynamic Signature Recognition is one of the highly accurate biometric traits. Live signature of the person is captured, hence it is possible to have dynamic characteristics of signature for matching purpose. The signature captured by digitizer gives information about dynamic nature of...
