摘要:
AbstractIn this note we examine certain sharpenings of the Tietze-Urysohn extension theorem. We prove, for example, that ifAis a closed subspace of a normal spaceXthen there is acontinuousextenderη:C*(A)→C*(X), whereC*(A)andC*(X)are the Banach spaces of continuous, bounded, real-valued functions onAandX, respectively. However, well-known examples show that we cannot arrange thatηis both continuous and linear, or thatηis an isometry.

摘要:
AbstractA graphic method is presented for constructing the spherical indicatrices of the tangent, principal-normal, and binormal of space curves described by intrinsic equations. Using this method, it will not be necessary to integrate the Serret-Frenet formulas. The indicatrices are obtained directly by mapping plane curves onto a unit sphere. This mapping requires the sphere to roll on the plane such that the locus of the contact point in the plane is the preimage and the corresponding locus on the sphere is the desired indicatrix. Equations for the plane curves are derived and procedures for performing the graphic mapping are outlined.
