Exploring Non-Orientable Topology: Deriving The Poincaré Conjecture And Possibility Of Experimental Vindication With Liquid Crystal, Victor Christianto, Florentin Smarandache Nov 2023

Exploring Non-Orientable Topology: Deriving The Poincaré Conjecture And Possibility Of Experimental Vindication With Liquid Crystal, Victor Christianto, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

This review investigates the potential of non-orientable topology as a fundamental framework for understanding the Poincaré conjecture and its implications across various scientific disciplines. Integrating insights from Dokuchaev (2020), Rapoport, Christianto, Chandra, Smarandache (under review), and other pioneering works, this article explores the theoretical foundations linking non-orientable spaces to resolving the Poincaré conjecture and its broader implications in theoretical physics, geology, cosmology, and biology.


Restoration And Balancing Of A Cross Section Of The Mt. Crandell Duplex, Waterton National Park, Canada, Danielle Sommerman, M. Scott Wilkerson Oct 2023

Restoration And Balancing Of A Cross Section Of The Mt. Crandell Duplex, Waterton National Park, Canada, Danielle Sommerman, M. Scott Wilkerson

Student Research

Cross-section balancing provides a useful tool for checking the potential viability of structural interpretations through complexly deformed terranes. Balanced cross sections contain structures that are similar to those observed in outcrop or on seismic profiles in the area, that can be restored to a realistic pre-deformational configuration of faults and undeformed strata where areas are preserved between the deformed and restored states, and whose development from the undeformed state can be described in a kinematically reasonable sequence. Quick-look inspection of cross sections greatly facilitates the balancing process by comparing corresponding hanging wall and footwall features (particularly focusing on ramps and …


An Analysis Of Clinopyroxene Reaction Rims As Assimilation Chronometers At Cinder Cone Volcano, Lassen National Volcanic Park, California, Annabelle Carozza Oct 2023

An Analysis Of Clinopyroxene Reaction Rims As Assimilation Chronometers At Cinder Cone Volcano, Lassen National Volcanic Park, California, Annabelle Carozza

WWU Honors College Senior Projects

Cinder Cone is a monogenetic cinder cone volcano located in Lassen National Volcanic Park, California. It erupted in 1666 CE and had three eruptive phases, each producing tephra and lava flows that ranged in style from Hawaiian (low explosivity) to Strombolian (moderate to high explosivity). This eruptive style variability at Cinder Cone was not caused by viscosity or volatile differences, and ascent rate has been proposed as a causal factor in the observed explosivity difference between phases. Ubiquitous quartz crystals are entrained within tephra and lava and were likely sourced from the assimilation of a granitic basement rock underlying the …

Kimberlites are volatile-rich, occasionally diamond-bearing magmas that have erupted explosively at Earth’s surface in the geologic past1,2,3. These enigmatic magmas, originating from depths exceeding 150 km in Earth’s mantle1, occur in stable cratons and in pulses broadly synchronous with supercontinent cyclicity4. Whether their mobilization is driven by mantle plumes5 or by mechanical weakening of cratonic lithosphere4,6 remains unclear. Here we show that most kimberlites spanning the past billion years erupted about 30 million years (Myr) after continental breakup, suggesting an association with rifting processes. Our dynamical …


New U–Pb Geochronology For The Central Atlantic Magmatic Province, Critical Reevaluation Of High-Precision Ages And Their Impact On The End-Triassic Extinction Event, Alisson L. Oliveira, Mark D. Schmitz, Corey J. Wall, James L. Crowley, Antomat A. Macêdo Filho, Maria Helena B. M. Hollanda Apr 2023

The end-Triassic extinction (ETE) event represents one of the ‘big five’ episodes of mass extinction. The leading hypothesis for the cause of the ETE is the intrusion of voluminous magmas of the Central Atlantic Magmatic Province (CAMP) into carbon-rich sediments of two South American sedimentary basins, around 201.5 Ma. The timing of dikes and sills emplacement, however, must be considered in light of age models from CAMP rocks occurring in North America. In this work, we present new high-precision ages for critical samples in NE Brazil (201.579 ± 0.057 Ma) and Canada (201.464 ± 0.017 Ma), in order to evaluate …
