Kuliah Kerja Mahasiswa (KKM) merupakan kegiatan pengabdian masyarakat yang harus ditempuh oleh mahasiswa S1. Kondisi pandemi covid mengubah konsep KKM biasa menjadi Tematik. Kegiatan ini berkonsep pada pendampingan mitra secara berkelanjutan di sekitar Universitas Serang Raya (Unsera) dan tempat tinggal mahasiswa. Pendampingan dilakukan dalam beberapa diantaranya: KKM-UM (Unsera Mengajar), KKM-...

In this paper, we introduce the notion of extended relaxed -monotonicity. We obtain existence solution of the generalized mixed equilibrium problems in reflexive Banach spaces with extended relaxed -monotonicity by using the KKM technique. Our results extend and improve the corresponding results in the existing literature.

In this paper, we introduce the concept of generalized relaxed αpseudomonotonicity for vector valued bi-functions. By using the KKM technique, we obtain some substantial results of the vector equilibrium problems with generalized relaxed α-pseudomonotonicity assumptions in reflexive Banach spaces. Several examples are provided to illustrate our investigations.

We apply the KKM technique to study generalized vector implicit variational inequality problem. Our results generalize the works of Huang and Li [8], Li and Huang [11], and represent variant of result of Lee and Farajzadeh [10]. We also obtain a version of best approximations theorem in cone metric spaces.

In this paper, we consider mixed vector variational-like inequality problems in the setting of topological vector spaces. We extend the concept of upper sign continuity for vector-valued mappings. Further, by exploiting KKM-Fan lemma, we establish some existence results for solutions of mixed vector variational-like inequality problems and show that the solution sets of these problems are compact.
