Approximate for the null distribution of a statistic caused by random combinations

Kulatunga, D.D.S.; Kudo, A.; Azuma, S. (Applied Statistics Association of Sri Lanka, 2000)
On the validity of three body model calculations

Dahanayaka, S.D.; Piyadasa, R.A.D. (Sri Lanka Association for the Advancement of Science, 2013)
The identity of Fermat equation and simple proof of Fermat’s last theorem for n=5

Pallewatta, P.G.M.O.; Piyadasa, R.A.D. (Sri Lanka Association for the Advancement of Science, 2013)
Proof of Fermat’s last theorem for n=5 and many odd primes

Ubeynarayana, C.U.; Dharmasiri, K.G.E.U.; Piyadasa, R.A.D. (Sri Lanka Association for the Advancement of Science, 2013)
The equality of Schrödinger’s Theory and Heisenberg’s S-matrix Theory

Silva, H.I.R.U. (Sri Lanka Association for the Advancement of Science, 2011)

The main aim of this work is to show that the energy discrete eigen values given by the Schrödinger’s theory and Heisenberg’s theory are the same. To obtain this result, we have used Parabolic co-ordinates to solve the ...
Physically meaningful zeros and poles of elastic S-matrix element

Amarasinghe, A.V.D.S.; Katunatileke, N.G.A.; Shadini, A.M.D.M. (Sri Lanka Association for the Advancement of Science, 2011)

It is found that an essential singularity is introduced at the origin of the complex k-plane in the S-matrix element in addition to the infinite number of zeros and poles apparently introduced due to the Coulomb potential. ...
Effect of long-range part of the potential on the elastic S-matrix element

Shadini, A.M.D.M.; Munasingha, J. (Sri Lanka Association for the Advancement of Science, 2011)

The quantum mechanical three-body Schrödinger equation can be reduced to a set of coupled differential equations when the projectile is easily breakable into two fragments and when scattering is a heavy stable nucleus. ...
Advanced plane geometry research – II

Amarasinghe, G.W.I.S. (Sri Lanka Association for the Advancement of Science, 2010)
Advanced plane geometry research – III: Alternative proofs for the standard theorems in plane geometry

Amarasinghe, G.W.I.S. (Sri Lanka Association for the Advancement of Science, 2010)
Advanced plane geometry research – I

Amarasinghe, G.W.I.S. (Sri Lanka Association for the Advancement of Science, 2010)
On theoretical description of the validity of a simple quantum mechanical three body model

Rathnayaka, D.A.; Piyadasa, R.A.D. (Sri Lanka Association for the Advancement of Science, 2014)
