Bulging Triangles: Generalization of Reuleaux Triangles

Norihiro Someyama

We introduce a bulging triangle like the generalization of the Reuleaux triangle. We may be able to propose various ways to bulge a triangle, but this paper presents the way so tha…

Type-2 Fuzzy Initial Value Problems for Second-order T2FDEs

Norihiro Someyama, Hiroaki Uesu, Kimiaki Shinkai +1

Type-2 fuzzy differential equations (T2FDEs) of order 1 are already known and the solution method of type-2 fuzzy initial value problems (T2FIVPs) for them was given by M. Mazandar…

Some Inclusion Relations for Fuzzy Sets

Norihiro Someyama

We give some inclusion relations for arbitrary fuzzy sets with reference to famous inequalities. In particular, we can know that the bounded sum and the algebraic product go well t…

Bounds and Gaps of Positive Eigenvalues of Magnetic Schrödinger Operators with No or Robin Boundary Conditions

Norihiro Someyama

We consider magnetic Schrödinger operators on a bounded region with the smooth boundary in Euclidean space . In reference to the result from Weyl's…

New Proofs of Triangle Inequalities

Norihiro Someyama, Mark Lyndon Adamas Borongan

We give three new proofs of the triangle inequality in Euclidean Geometry. There seems to be only one known proof at the moment. It is due to properties of triangles, but our proof…
