We give some examples of slant submanifolds of cosymplectic manifolds. Also, we study some special slant submanifolds, called austere submanifolds, and establish a relation between minimal and anti-invariant submanifolds which is based on properties of the second fundamental form. Moreover, we give an example to illustrate our result. 1. Introduction. The notion of a slant submanifold of an almost Her- mitian manifold was introduced by Chen (7). Examples of slant submanifolds of C 2 and C 4 were given by Chen and Tazawa (12), while those of slant sub- manifolds of a Kahler manifold were given by Maeda, Ohnita and Udagawa (21). On the other hand, A. Lotta (19) defined and studied slant submanifolds of an almost contact metric manifold. He also studied the intrinsic geometry of 3-dimensional non-anti-invariant slant submanifolds of K-contact mani- folds (20). Later, L. Cabrerizo and others investigated slant submanifolds of a Sasakian manifold and obtained many interesting results (2) and examples. Slant submanifolds of cosymplectic manifolds have been studied in (16). Lotta (19) has proved that a non-anti-invariant slant submanifold of a contact metric manifold must be odd-dimensional. This motivated us to find examples of slant submanifolds of a cosymplectic manifold with dimension greater than or equal to 3. In this paper we give some examples of mini- mal and non-minimal slant submanifolds with dimension 3. We also obtain sufficient conditions for slant submanifolds to be either austere or minimal.
