Penelitian ini dilatarbelakangi oleh rendahnya keterlibatan siswa sehingga berdampak pada hasil belajar kelas VIII SMP. menggunakan pendekatan kualitatif dengan penelitian tindakan kelas, terdiri dari empat langkah yaitu persiapan, pelaksanaan, observasi, dan refleksi. Hasil matematika meningkat karena yang telah dilakukan. dilakukan terhadap 44 VIII-5 genap satu semester di salah SMP Bekasi. T...

In the present paper, we study some properties of fuzzy norm of linear operators. At first the bounded inverse theorem on fuzzy normed linear spaces is investigated. Then, we prove Hahn Banach theorem, uniform boundedness theorem and closed graph theorem on fuzzy normed linear spaces. Finally the set of all compact operators on these spaces is studied.

convexity theory and duality theory are important issues in math- ematical programming. within the framework of credibility theory, this paper rst introduces the concept of convex fuzzy variables and some basic criteria. furthermore, a convexity theorem for fuzzy chance constrained programming is proved by adding some convexity conditions on the objective and constraint functions. finally,...

in this paper the bagley-torvik equation as a prototype fractional differential equation with two derivatives is investigated by means of homotopy perturbation method. the results reveal that the present method is very effective and accurate.

In the summer of 2004, I participated in an REU program at East Tennessee State University. Many of the investigations I worked on were successful, leading to 4-6 papers, some of which have been submitted, and others are still in the writing process. There are many unanswered questions left in the investigations that I was conducting, and some of the work already done is not complete. Given tha...

We introduce the notion of a matron M = {Mn,m} whose submodules M∗,1 and M1,∗ are non-Σ operads. We construct a functor from PROP to matrons and its inverse, the universal enveloping functor. We define the free matron H∞, generated by a singleton in each bidegree (m, n) 6= (1, 1), and define an A∞-bialgebra as an algebra over H∞. We realize H∞ as the cellular chains of polytopes {KKn,m = KKm,n}...
