Motivated by the lower central series of three important subgroups of the mapping class group, and by the recent ideas of p-branes in string theory, we introduce a notion of blinks and BL-type invariants of oriented integral homology 3-spheres. In the rst part of the paper we show that the ltrations (on the vector space generated by oriented integral homology 3-spheres) coming from these subgro...

In the papers Minčić (1973) [15], Minčić (1977) [16], several Ricci type identities are obtained by using non-symmetric affine connection. Four kinds of covariant derivatives appear in these identities. In the present work, we consider equitorsion geodesic mappings f of two spaces GAN and GRN , where GRN has a non-symmetric metric tensor, i.e. we study the case when GAN and GRN have the same to...

In this paper we prove a Radó type result showing that there is no univalent polyharmonic mapping of the unit disk onto whole complex plane. We also establish connection between boundary functions harmonic and biharmonic mappings. Finally, show how close-to-convex can be constructed from convex mapping.

Accurate and up-to-date maps of seagrass biodiversity are important for marine resource management but it is very challenging to test the accuracy of remote sensing techniques for mapping seagrass in coastal waters with variable water turbidity. In this study, Worldview-2 (WV-2) imagery was combined with field sampling to demonstrate the capability of mapping species type, percentage cover, and...

The main objective of this paper is to study the Euclidean displacement of a 5-DOF parallel mechanism performing three translation and two independent rotations with identical limb structures-recently revealed by performing the type synthesis-in a higher dimensional projective space, rather than relying on classical recipes, such as Cartesian coordinates and Euler angles. In this paper, Study's...

Determination of stockpile weight and stockpile inventory are critical to any quarry or mining operation, whether it is required by accounting firms or used internally for the quarterly balance of production and sales. Generally, errors and problems originate from two factors. Volume of stockpile that is traditionally worked out from the mapping results has a low accuracy due to irregular shape...

In this paper, we consider double sequence iteration processes for strongly $rho$-contractive mapping in modular space. It is proved, these sequences, convergence strongly to a fixed point of the strongly $rho$-contractive mapping.

Although story mapping strategy has been shown to be beneficial in many reading comprehension classes, the benefits of this technique have not been thoroughly investigated in L2 writing research. The small number of previous studies (e.g., Li, 2007; Brunner, 2010) have found the potential benefits of using story mapping strategy on students’ writing performance, but they did not focus on differ...
